PL/M-80-Compiler, V4.0, for SME
Operation of Compiler
Requirements
-SME Standard configuration with 64 Kbyte RAM - Extended
Storage
-Console (CRT or TTY)
-Floppy Disk Storage
-ISIS II Operating System
Files
Input files: -Source
Program file
-INCLUDE
- Files (Optional)
Ouput files: Object
Code File (Optional)
Compiler
Listing File (Optional)
-Information
File for the Program IXREF (Optional)
Work files -PLMTX1.TMP
-PLMTX2.TMP
-PLMAT.TMP
-PLMXRF.TMP
-PLMNMS.TMP
Attention: The temporary filenames created by the
PL/M-80-Compiler are reserved and will be reused by the compiler. Work Files
default to Drive 1 unless the control WORKFILES is used to re-direct.
Typical procedure to do program development on an SME with
2 Drives:
1. Switch on
the SME
2. Insert the
System Diskatte with the PL/M-80-Compiler in Drive 0.
3. Insert a
user (Data-) Diskette in Drive 1
4. Boot the
ISIS-II-Operating system
5. Put the
Primary Program in Drive 1. Use a text
editor to edit.
6. Compile the
Program with Hilfe the PL/M-80-Compiler
7. Link (LINK)
with other Object code modules
Hint: PL/M-80-Program, produced from modules must be
linked together with PLM80.LIB linked in last.
8. Locate
(LOCATE) the Object code to fixed memory locations
9. Load and
Execute the Program

2.2 Invoking and
Parameters
Invoking:
[:Fn:]PLM80 <source file name> [<parameters>]
where n is the
Drive Number between; 0<=n<=9
Parameters:
Hint: There’s two ways to use Control Parameters, one in the
Invocation line and the other on Control lines in the Source Program (when used
on a control line the control must start with a Dollar sign $).
1. primary: - may be used in the invocation line of the compiler
- or in the very first line of the source
file
(Primary parameters are marked in the
Table below with an * ).
2. general: - may be used in the invocation line of the compiler
-
may be used
on any line within the source file (with leading ‘$’)
-
such as ‘$include
includefile, $list / $nolist’.
