DUMP
Syntax:
DUMP filespec
Explanation:
DUMP displays the contents of a file in hexadecimal and ASCII format.
Example:
A>DUMP ABC.TEX
|
GENCOM
Syntax:
GENCOM COM-filespec RSX-filespec ... [LOADER NULL SCB=(offset,value)]
Explanation:
The GENCOM command creates a special COM file with attached RSX files. The GENCOM command can also restore a previously GENCOMed file to the original COM file without the header and RSX's. GENCOM can also attach header records to COM files.
GENCOM
OPTIONS
- LOADER
- sets a flag to keep the program loader active.
- NULL
- indicates that only RSX files are specified. GENCOM creates a dummy COM file for the RSX files. The output COM filename is taken from the filename of the first RSX-filespec.
- SCB=(offset,value)
- sets the System Control Block from the program by using the hex values specified by (offset,value).
GENCOM
EXAMPLES
A>GENCOM MYPROG PROG1 PROG2
Generates a new COM file MYPROG.COM with attached RSX's PROG1 and PROG2.
A>GENCOM PROG1 PROG2 [NULL]
Creates a COM file PROG1.COM with RSX's PROG1 and PROG2.
A>GENCOM MYPROG
GENCOM takes MYPROG.COM, strips off the header and deletes all attached RSX's to restore it to its original COM format.
A>GENCOM MYPROG PROG1 PROG2
GENCOM looks at the already-GENCOMed file MYPROG.COM to see if PROG1.RSX and PROG2.RSX are already attached RSX files in the module. If either one is already attached, GENCOM replaces it with the new RSX module. Otherwise, GENCOM appends the specified RSX files to the COM file.

HEXCOM
Syntax:
HEXCOM filename
Explanation:
The HEXCOM Command generates a command file (filetype .COM) from a .HEX input file. It names the output file with the same filename as the input file but with filetype .COM. HEXCOM always looks for a file with filetype .HEX.
Example:
A>HEXCOM B:PROGRAM
Generates a command file PROGRAM.COM from the input hex file PROGRAM.HEX.

LIB
Syntax:
LIB filespec[IMPD]
LIB filespec[IMP]=filespecmodifier,filespecmodifier ...
Explanation:
A library is a file that contains a collection of object modules. Use the LIB utility to create libraries, and to append, replace, select or delete modules from an existing library. Use LIB to obtain information about the contents of library files.
LIB creates and maintains library files that contain object modules in Microsoft REL file format. These modules are produced by Digital Research's relocatable macro-assembler program, RMAC, or any other language translator that produces modules in Microsoft REL file format.
You can use LINK-80 to link the object modules contained in a library to other object files. LINK-80 automatically selects from the library only those modules needed by the program being linked, and then forms an executable file with a filetype of COM.
LIB
OPTIONS
- I
- The INDEX option creates an indexed library file of type .IRL. LINK-80 searches faster on indexed libraries than on non-indexed libraries.
- M
- The MODULE option displays module names.
- P
- The PUBLICS option displays module names and the public variables for the new library file.
- D
- The DUMP option displays the contents of object modules in ASCII form.
LIB
MODIFIERS
Use modifiers in the command line to instruct LIB to delete, replace, or select modules in a library file. Angle brackets enclose the modules to be deleted or replaced. Parentheses enclose the modules to be selected.
LIB Modifiers
- Delete
- <module=>
- Replace
- <module=filename.REL>
If module name and filename are the same this shorthand can be used:
<filename>
- Select
- (modFIRST-modLAST,mod1,mod2,...,modN)
LIB
EXAMPLES
A>LIB TEST4[P]
Displays all modules and publics in TEST4.REL.
A>LIB TEST5[P]=FILE1,FILE2
Creates TEST5.REL from FILE1.REL and FILE2.REL and displays all modules and publics in TEST5.REL.
A>LIB TEST=TEST1(MOD1,MOD4), TEST2(C1-C4,C6)
Creates a library file TEST.REL from modules in two source files. TEST1.REL contributes MOD1 and MOD4. LIB extracts modules C1, C4, and all the modules located between them, as well as module C6 from TEST2.REL.
A>LIB FILE2=FILE3<MODA=>
Creates FILE2.REL from FILE3.REL, omitting MODA which is a module in FILE3.REL.
A>LIB FILE6=FILE5<MODA=FILEB.REL>
Creates FILE6.REL from FILE5.REL, FILEB.REL replaces MODA.
A>LIB FILE6=FILE5<THISNAME>
Module THISNAME is in FILE5.REL. When LIB creates FILE6.REL from FILE5.REL the file THISNAME.REL replaces the similarly named module THISNAME.
A>LIB FILE1[I]=B:FILE2(PLOTS,FIND,SEARCH-DISPLAY)
Creates FILE1.IRL on drive A from the selected modules PLOTS, FIND, and modules SEARCH through the module DISPLAY, in FILE2.REL on drive B.

LINK
Syntax:
LINK d:filespec,[options]=filespec[options],...
Explanation:
LINK combines relocatable object modules such as those produced by RMAC and PL/I-80 into a .COM file ready for execution. Relocatable files can contain external references and publics. Relocatable files can reference modules in library files. LINK searches the library files and includes the referenced modules in the output file. See the CP/M 3 Programmer's Utilities Guide for a complete description of LINK-80.

- $Od
- Destination of of object file; d can be Z or disk drive A-P. Default is to same drive as first file in the LINK-80 command.
- $Sd
- Destination of symbol file; d can be Y or Z or disk drive A-P. Default is to same drive as first file in LINK-80 command.
LINK
EXAMPLES
A>LINK b:MYFILE[NR]
LINK-80 on drive A uses as input MYFILE.REL on drive B and produces the executable machine code file MYFILE.COM on drive B. The [NR] option specifies no symbol table file.
A>LINK m1,m2,m3
LINK-80 combines the separately compiled files m1, m2, and m3, resolves their external references, and produces the executable machine code file m1.COM.
A>LINK m=m1,m2,m3
LINK-80 combines the separately compiled files m1, m2, and m3 and produces the executable machine code file m.COM.
A>LINK MYFILE,FILE5[s]
The [s] option tells LINK-80 to search FILE5 as a library. LINK-80 combines MYFILE.REL with the referenced subroutines contained in FILE5.REL on the default drive A and produces MYFILE.COM on drive A.

MAC
Syntax:
MAC filename $options
Explanation:
MAC, the CP/M 3 macro assembler, reads assembly language statements from a file of type .ASM, assembles the statements, and produces three output files with the input filename and filetypes of .HEX, .PRN, and .SYM. Filename.HEX contains INTEL hexadecimal format object code. Filename.PRN contains an annotated source listing that you can print or examine at the console. Filename.SYM contains a sorted list of symbols defined in the program.

XREF provides a cross-reference summary of variable usage in a program. XREF requires the .PRN and .SYM files produced by MAC or RMAC for input to the program. The SYM and PRN files must have the same filename as the filename in the XREF command tail. XREF outputs a file of type .XRF.
Examples:
A>XREF b:MYPROG
A>XREF b:MYPROG $P
