IBM Pascal Compiler Aug81 pdf (via: Bitsavers’ Index of /pdf/ibm/pc/dos)

Wow, I didn’t know that IBM had their own DOS based Pascal compiler for the PC in 1981, but they did, and BitSavers just uploaded their manual

It is part of their “Personal Computer Computer Language Series”
From the era of DOS Pascal compilers before Turbo Pascal.

MS QuickPascal was probably the reason Turbo Pascal 5.5 was released. QP had come out shortly before it, and used Wirth’s ObjectPascal syntax. TP 5.5 was released without any useful OO framework, and only TP 6 came with Turbo Vision. MSQP did not sell very well, IIRC.

It was in fact the reason to release early. Borland had been working on that compiler for quite a while (closely looking at Object Pascal from Apple) when Microsoft came out
Just learned from http://programmers.stackexchange.com/questions/96788/what-was-the-life-span-of-quick-pascal that Quick Pascal was actually a scaled down version of Microsoft Pascal, but with added OO features.
BTW: You posted an almost similar statement here years ago: http://www.delphigroups.info/2/8b/448391.html (;

thanks. updated.

Microsoft had a Pascal compiler also. In the early DOS days I used to program in MS Pascal and Turbo Pascal for the same project.
Turbo Pascal had only a segment for code but several for data whereas MS Pascal had only one segment for data but several for code.
Thus data input modules were written in MS Pascal to have enough code space for data validation, whereas data manupilation modules were written in Turbo Pascal due to needed memory for intermediate data. Large programs were only possible with Turbo Pascal 4.0 and above with
the ability to create overlays.
jpluimers said
Nice!
Was that Microsoft Quick Pascal you used, or another Microsoft Pascal compiler?
Franz-Leo Chomse said
No. The Original one. (The above IBM Pascal should be an OEM version)
