IBM Pascal Compiler 1.00
|
|
------------------------
|
|
|
|
When the IBM Pascal Compiler 1.00 was originally released in August 1981, the standard IBM PC contained at most
|
|
two diskette drives (no hard drive), so compiling Pascal programs required using a "scratch disk" in drive B:
|
|
and then inserting each of the three 160Kb Pascal Compiler disks into drive A: to complete the compilation and
|
|
linking process. Moreover, the user was required to copy LINK.EXE from their PC-DOS 1.00 diskette (the only version
|
|
of PC-DOS available at the time) to the third disk.
|
|
|
|
To make life a bit simpler (but only a bit), we've combined the contents of all three diskettes onto a 360Kb "Combined"
|
|
diskette, along with LINK.EXE from PC-DOS 1.00. Here's the [DiskDump](/modules/diskdump/) command used to produce the
|
|
diskette image:
|
|
|
|
diskdump --path="archive/PAS1/PAS1.EXE;PASKEY;ENTX6S.ASM;FILKQQ.INC;FILUQQ.INC;archive/PAS2/PAS2.EXE;
|
|
archive/PAS3/PASCAL;PASCAL.LIB;../../../../dos/ibm/1.00/archive/PCDOS100/LINK.EXE" --format=json --label=PASCAL100
|
|
--output=PASCAL100-DISKS.json --manifest
|
|
|
|
It's important to use the original PC-DOS linker, because not all linkers will process IBM Pascal 1.00 object files
|
|
properly. Given this dependency, it's odd that IBM didn't simply distribute the PC-DOS 1.00 linker on the third IBM
|
|
Pascal disk; there was certainly room for it, so it wouldn't have cost anything, and it would have reduced the risk
|
|
of using a newer and potentially incompatible linker.
|
|
|
|
NOTE: We do not have copies of the three original distribution disks. However, based on information in IBM's Pascal
|
|
Compiler documentation, we were able to recreate the contents of the disks. The file dates were arbitrarily selected
|
|
from the August 1981 time frame.
