13. For communication with devices or computers outside the CAMAC system a simple parallel or serial e g the RS 232 standard interface is usually employed In contrast to the controller described above the dumb crate controller has little or no local intelligence and is primarily to translate commands and data from an external host computer to the form required by the Dataway and the CAMAC modules The type of controller required depends upon the application Controllers are available which allow several crates to be controlled 110 in a serial or parallel arrangement by single host computer smart crate controller The types of data and their rate of transfer must also be considered when selecting a controller If a dumb con troller is selected it must be compatible with the bus structure the input output conventions and the signal protocol of the host computer Sec 2 5 CAMAC Commands As mentioned in the previous section the CAMAC modules are con trolled via commands issued by the crate controller Each module is addressed by its station number N Within each module any one of 16 subaddresses can be specified by a 4 bit subaddress code A Ag generated by the controller There are 32 CAMAC commands called F codes which are selected by a 5 bit command code oF asFosF ig and directed to an individual module and subaddress by the N and A codes The response from the module to this comma

20. An ex ample of a data analysis program is discussed in Appendix D As new hardware is acquired it can be added to the software mand structure simply by adding the appropriate information to the con figuration file and adding the command and controlling routines to the main calling program The hardware need not be limited to the CAMAC equipment At present the software is written as a series of overlaid segments due to the limited amount of memory in the 11 04 minicomputer When additional memory becomes available all program segments could be resi dent at once This would eliminate the delay caused when segments are overlaid The execution time of the graphics routines could be improved by writing these routines in assembly language and linking them into the BASIC language These routines would then be available as callable functions as are those discussed in Sec 4 5 and Appendix B The Tek tronix 4025 terminal can be driven by the older 4010 style commands 81 82 These commands in more compressed form which is less convenient to use but considerably faster than the 4025 commands for the present application If the graphics routines were written in 4010 style com mands and then linked into BASIC both speed and convenience would be preserved Some improvements and additions could be made to the user functions that have been added to the BASIC language As a safety feature a routine could be written

60. Because the POKE STOB FAST and especially EXEC can change memory contents they should be used with caution A large amount of error checking is performed mak ing the subroutines appear more complicated than they are Error re covery is attempted wherever possible except in FAST It is incon sistent with the purpose of FAST to spend a lot of time correcting errors so the routine simply crashes back to BASIC giving an error mes sage The most likely source of error is that the arguments were in floating point format not integer format EXEC is a powerful tool for developing new subroutines without going through the lengthy process of assembling and linking BASIC Ma chine code is entered directly into vacant memory locations see FREM and execution commences at the address given in the call to EXEC One argument can be passed to the machine language code via the call to EXEC it is placed in register R3 when execution commences Other arguments can be passed both ways by PEEK and POKE The code must end with RTS PC 207 octal or 135 decimal Because this method of calling subroutines is so general it is sub ject to operator error and is not recommended for inexperienced users or for permanent systems 115 116 The assembly and linking procedures followed are given in Appendix F of the BASIC Language Reference Manual The subroutine set GETARG in Appendix D of the BASIC manual is used in t
