-
- SUPERMIT (TM), Vers. 3.0
-
- For all versions of CP/M 2.2 and most 8080/Z80 relatives.
- (CP/M 3, CP/M+, ZCPR, probably MP/M, etc.)
-
-
- [] A batch-job programming language, similar to BASIC.
-
- [] Includes several uniquely flexible, stand-alone utilities.
-
- [] SUPERMIT Version 3.0--
-
- o Provides virtually universal compatibility with CP/M's
- "family and friends."
-
- o Fixes miscellaneous, minor problems in earlier versions.

-
- BACKGROUND: Batch jobs
-
-
- The SUBMIT utility of CP/M lets your computer do your typing for you.
-
- Instead of typing each of a sequence of individual commands at the time
- needed, you can put all the commands into a disk file, and tell CP/M to
- get commands from disk instead of the console. Then, while your system
- is busy doing all the work, you put up your heels, relax, and read the
- newspaper.
-
- If you have a set of commands that can be expressed as a straight-forward,
- once-through sequence of steps, a standard SUBMIT job will do the trick.
-
- But unlike a true program, such a job isn't very bright. It can't--
-
- 1) Perform a job step only if conditions warrant.
-
- 2) GO TO different job steps.
-
- 3) Create and manipulate dynamic variables.
-
- 4) Use arrays, loops, or other basic programming structures.
-
- In effect, standard batch jobs operate as though each command were being
- read off the top of a deck of punched cards, and then discarded.
-
- SUPERMIT rescues batch jobs from the era of the punched card.
-
-
-
- <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
-
- THE SUPERMIT CONCEPT
-
-
- SUPERMIT gives batch jobs a "BASIC-like" capability.
-
- SUPERMIT brings to SUBMIT files the three essential elements of
- programming--
-
- o IF...THEN...ELSE
- o GOTO
- o dynamic variables
-
-
- The result is a quantum leap in the power of batch jobs.
-
- * IF...THEN...ELSE allows job steps to be executed or bypassed
- according to environmental conditions, including "result" codes
- from previous steps.
-
- * GOTO can jump to any line within the job.
-
- * FOR...NEXT, DO...WHILE, and ON...GOTO structures can be created
- to allow looping and branching among job steps.
-
- * Nesting is available for IF...THEN...ELSE, for commands, and even
- for variables.
-
- * String variables can be up to 120 characters long.
-
- * Single-dimensioned string arrays are supported.
-
- * Numeric variables can have up to 8-digit precision.
-
- * Filenames can be added, subtracted, multiplied, and/or divided.
- (Wild cards are supported.)
-
- * Filename characters can be replaced, transposed, and/or deleted.
- (Wild cards are supported.)
-
- * Subroutines and subjobs are feasible.
-
-
- None of this diminishes the space available in main memory to run
- programs. All SUPERMIT modules are totally transient.
-
- And like BASIC, the SUPERMIT modules help job-writing by providing
- extensive run-time diagnostics.

- INSTRUCTIONS
-
-
- Condensed instructions for each module are displayed by that module
- when it is executed without parameters. For instance, to display
- instructions for IF.COM, simply type--
-
- IF<cr> where "<cr>" means the RETURN or ENTER key.
-
- The instructions also tell how to get the complete SUPERMIT User's
- Manual for $9.95.
-
- We recommend purchasing the User's Manual, which contains additional
- instructions, helpful shortcuts, and programming tips. Items include--
-
- o How to write FOR...NEXT and other loops.
-
- o How to restart a job at any desired step without reprogramming.
-
- o How to create executable libraries that are more compact
- than .LBR files, and yet can be changed with any text editor.
-
- o How to write conditional compile/link/go jobfiles.
-
- o How to write complex conditionals with IF.COM.
-
- o How to use multiple string-operations to rename any file.
-
- o How you might inadvertently disable the nesting capability
- of IF.COM and #.COM.
-
- o How to create and invoke jobstep subroutines.
-

-
- "+" VERSIONS
-
-
- The plus versions of IF.COM and #.COM were adapted for compatibility
- with CP/M+. They are fully usable with CP/M 2.2 and most of its clones.
-
- The plus versions are identical in function to their counterparts, but
- do not recognize the resident commands of the CCP. In standard CP/M 2.2,
- these resident commands are TYPE, ERA, USER, SAVE, and DIR.
-
- If any of these resident commands are needed for use with the plus
- versions, a suitable utility program can be created or obtained that
- performs the same function.
-
- For instance, XDIR.COM or SD.COM may be used instead of DIR. And
- instead of the ERA command, a simple four-line assembly language
- program can be created, called ERA.COM. (Complete instructions for
- creating ERA.COM are given in the SUPERMIT User's Manual.)
-
-
-
- <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
-
- WHICH MODULES SHOULD I USE?
-
-
- Three tests for compatibility are provided: SUPTEST1.SUB, SUPTEST2.SUB,
- and SUPTEST3.SUB. They are numbered in order of decreasing functionality.
-
- Begin testing by reading the test instructions contained in SUPTEST1.SUB,
- then executing that test. If the test is successful, you can use modules
- IF, #, GOTO, and SET. This set of modules comprises the fullest set of
- SUPERMIT functions.
-
- If SUPTEST1.SUB is not completely successful, read the instructions contained
- in SUPTEST2.SUB and then execute it. If this test is successful, you can
- use modules IF+, #+, GOTO, and SET. This set of modules contain essentially
- the same functions as those in SUPTEST1.SUB.
-
- (The "plus" modules are implemented in a different manner from the others,
- to make them compatible with a wider variety of CP/M look-alikes. The trade-
- off is that the "plus" modules cannot execute the resident commands of the
- CCP: TYPE, DIR, ERA, USER, and SAVE.)
-
- If SUPTEST2.SUB encounters an error, examine and execute SUPTEST3.SUB.
- This is equivalent to SUPTEST2.SUB without the GOTO module. (The SUPERMIT
- manual tells how to emulate GOTO if your system cannot use the GOTO module.)
-
- No errors should occur when executing SUPTEST3.SUB. If any do, please
- contact Logic Associates at the address given below.
