4. Programming the two computers to talk to each other is more difficult than attaching a printer to a computer Both devices are designed to be the host device and now one must be taught to be subservient First the cables have to be matched Unless you have the Option 001 model of the serial interface both computer interfaces are probably inclined to send information on pin 3 and receive it on pin 2 in which case you will need an adaptor cable to cross wire pins 2 and 3 Next the data transmission characteristics have to be matched Baud rate parity data bits and stop bits This may require some experimentation Finally you will need two programs one to send the data and another to receive it A simple approach is to select no protocol in both interfaces and to program a delay 1 on the sending computer after each transmitted line or block of data to give the receiving program enough time to edit it and store it in memory or in a disk file If you want to experiment with data transfers using a protocol to control the data transfer keep in mind that the ability to program a protocol on the HP serial interface and on microcomputer interfaces in general only works when sending data As a receiver of data the serial interface cannot cooperate with the XON XOFF or ENQ ACK as it does when sending data to a printer Your HP program which processes received data must handle it In this regard the flexibility of the I O ROM makes

7. A program that executes in less than 5 seconds on a mainframe can require more than 15 minutes on the HP 86 The same relative time is required for the compilation of the program However the 86 is not a mainframe and if you ve got the time p does get the job done very nicely In implementing and using p SYSTEM FORTRAN on my Micro I had to shift from use of FORTRAN IV which is what I had been using and educate myself in the ways of FORTRAN 77 used by p SYSTEM During this process I noticed some things which I felt were shortcomings of either the system or its instruction manuals I ve listed some of these below under the heading of Miller s Frustrations and Aggravations with the p SYSTEM o The p SYSTEM FORTRAN reference manual contains numerous valueless comments such as The FORTRAN compiler is invoked as the Pascal compiler would be Since I know nothing of Pascal this type of comparison didn t help me one bit in understanding the function they were trying to describe o Both the p SYSTEM introductory manual and the operating system reference manuals contain indexes a definite help to users The FORTRAN manual has no index What fun In addition the manual is very short on examples especially those that would clearly illustrate the various types of FORTRAN READ AND FORMAT statements And just to make things even more interesting after page 15 the page numbers no longer correspond to the page numbers specified in the
8. MERGE and use the various other features I had on my old HP85 AP ROM But there is another problem here The AP ROM doesn t like to reside in the same machine with the UTIL 1 binary program I use for a lot of formatting One of the big problems is that they have an extended LINPUT command in the AP ROM which is quite different from the LINPUT in UTIL 1 The entry of a step using the extended LINPUT command causes an instant dump of the entire program if I am using UTIL 1 in the same program I brought this to the attention of the HP rep and have received neither help nor sympathy and NEWSS80S Issue 10 Page 17 no hope of ever getting things straightened out Probably related to the previous problem is the fact that my keyboard will lock up from time to time when I want to rerun a long program and am sitting at an END step a few thousand program steps from the beginning All that happens when I press RUN is that the little power light starts blinking and the keyboard locks up No amount of reset or anything else will get me out of the loop If I do a re load from the disc it is happy to run again With the AP ROM out of the machine everything runs fine Apparently the word PAGE has been reserved by the AP ROM but is not discussed in the manual It s my great luck that I have about 20 programs in which I use PAGE as a numerical variable Of course I can t use the RENAME VARIABLE command in the AP ROM to change it because it won t accept
9. block of data can be sent The second method aids printer performance by striving toward constant operation of the printer With the ENQ ACK method the printer empties its buffer and finding the ENQ character as the last character it sends the signal to resume data transmission A small loss of time occurs while waiting for the first character of the next block to be sent With the XON XOFF also known as DC1 DC3 method a printer can be programmed to send the XOFF character ASCII 19 when its buffer becomes near full and to later send the XON character ASCII 17 when it becomes near empty The computer listening for the XOFF while sending data stops its transmission before the printer s buffer overflows Then waiting for the XON it sends more data in time to replenish the printer s buffer before it runs out Attaching an HP 2601A Printer Let s say you have the HP 2601A daisywheel printer An Application Note 75953 7816 has been published on the subject and it is explained here It specifies a series of SET I O statements to be executed prior to printing anything We ll take them one by one SET I O 10 2 5 Assuming you have not changed the default select code from 10 this statement places into control register 2 the value 5 It tells the interface that there are no modems operating between the computer and the printer i e it fakes out the interface making it believe that the modem is always ready and it is always clear to send
10. if the system had simply reported that a file was missing There are a few other problems and irritations I ve encountered along the way with the p SYSTEM but I ve found I can live with them If however I was to identify the one feature of the system that is most disappointing it would be the slowness of program execution I understand this slowness stems in part from the fact that the compiler produces a p code that must be interpreted at run time while other FORTRAN compilers produce machine language which runs much faster I also realize that p SYSTEM was designed for optimum portability between computers but I would gladly settle for the relatively good portability of FORTRAN 77 source code if it would mean reduced run times My overall attitude toward p SYSTEM is that although it does have its shortcomings I m mighty glad to have the system to work with I would like however to be able to look forward to improvements on a future release If they can speed up the compilation and execution times they will have a real winner BREAKER FOR BREAKPOINT BY DAVID EFRON In case you looked carefully the Assembler Breakpoint Subroutine published in issue 9 contains an error Using it as shown would clobber the registers numbered 70 77 and the breakpoint table would repeat the 20 s where the 70 s should be I was going to supply the lines to correct this when a phone call made me forget the whole thing There is a better way to do a
11. locations I also discovered that the compiler does not detect the lack of a closing parentheses in a FORMAT statement An error message does correctly report it at run time o When executing your programs under p SYSTEM it is necessary to have all your personal program libraries listed in a file named USERLIB TEXT This point is not mentioned in the FORTRAN manual and it s possible to waste many hours before realizing that the explanation is in the p SYSTEM Operating System Reference Manual It would help if this information were in the FORTRAN user s manual o In executing a program if an attempt is made to write to a file a REAL variable that has not yet had a value assigned to it then a Floating Point Error message appears This statement is not especially helpful in diagnosing the problem o p SYSTEM has a RAMDISC feature which I use for storing data files and libraries to be utilized by an executing program This reduces execution time significantly On one occasion my program attempted to read from a data file not in the system There was no END parameter in the READ statement and the error message 698 End of file encountered on read with no END option appeared I added the END parameter The program then ran with no error messages but of course it also produced nothing of value because there was no input When the missing file was added to RAMDISC the program ran fine It would have helped
12. table of contents Definitely a just plain careless feature o The p SYSTEM FORTRAN manual carries no information regarding the command to skip to a new page on the printer Hewlett Packard customer service helped me with this one The p SYSTEM will not handle special characters thus the use of the CHAR nn form is necessary I have an IDS Prism 132 printer which uses control code 12 for advancing to the next top of form Other printers may have other character code requirements The command to skip to a new page on my printer turned out to be WRITE IPRNT A CHAR 12 Once you learn this technique the door is open for using all the special control features of your printer o The p SYSTEM FORTRAN compiler offers the option of displaying errors on screen or writing them to a file you can later edit or print out When using the error display option you can continue to compile after an error is displayed or you can enter the edit mode on the source listing being compiled to correct the error When editing is elected the cursor is supposed to point to the line containing the error but unfortunately it consistently points to the wrong line and the line number it lists is of little help in trying to investigate NEWSSOS Issue 10 Page 14 the problem especially in large programs I now find it preferable to use the write to file option almost exclusively since this option provides a good summary of errors and their

27. o the serial interface part number HP 82939 don t despair don t reach for the 10 pound hammer as a solution an explanation of serial communications and how to use the serial interface might help in connecting it and expanding its usefulness A Sexual Problem The serial interface comes in male and female genders Which one to order depends on how it is to be mated The standard cable is female usually connecting to a peripheral device such as a printer which normally has a male connector Nevertheless there are exceptions to this general rule and they will require some digging through the printer s manual The Option 001 model is male which normally connects to a telecommunications modem but which can also be used to directly link one computer to another Let s work with the standard model and hook up a printer which performs serial data communications If you have the Option 001 interface you will find that it can be mated with the printer anyway A sex change operation is possible Have a short cable constructed which has a female connector on each end pass wires between pins 1 2 3 7 and 20 but cross connect pin 2 on one side with pin 3 on the other and vice versa and naturally if your printer uses other pins make sure that those wires are also passed through the cable adaptor Voodoo Magic These pins and the electronic chanting known as protocol enable the computer and printer to talk to each other The printe

29. r usually listens on pin 3 and it talks on pin 2 Normally that is what the computer does also but they both cannot do that if they are to communicate Modems are devices which oftentimes are used to solve that problem One would typically accept digital data from the computer on pin 2 and MODulate it with a frequency for transmission over a telephone network Another would receive that information DEModulate it then send the digital data through pin 3 of the cable which links it to the printer When the printer talks back to the computer the modems perform in the same way but the direction of the data path is reversed The printer s data 1s still sent out on pin 2 converted received by the other modem and sent to the computer on pin 3 Essentially the Option 001 serial interface is designed to operate in a remote telecommunications mode as described above In contrast the standard model is designed to be used in situations where the modems are not used such as attaching a printer to a computer in a local setting The standard Introducing FILE MOVE R and Four more UTILITIES for the HP 846 87 FILE MOVER Is a complete disc management utility program ts powerful tile handling tunctions its improved two column catalog display and its disc ia tistics tunction make it a handy tool for any user The un purge funchan alone Can prove its worth when a program or data nle ts lost through an accidental purge
