Hello Darren,
I don't know about CIS Cobol, I'll have to have a dig about that. I have a version of Cobol from some time ago, also, there was a copy of MS Cobol in with the software on the DOM supplied with JonB's uIDE device.
Was there a specific reason you were looking for the CIS version, as opposed to anything else?
For this sort of thing, if the implementation was OK for CP/M 2 or 3, then I'd expect it to be OK for the PCW, which is sufficiently standard CP/M. Those systems that do have a specifically Amstrad/PCW version are systems that require setting up for screen/terminal codes for things like CLS, cursor position, reverse video and things like that. So Wordstar does, dBase II does, any spreadsheet probably does. Most languages do not, as they'd expect you to create your own functions for that anyway.
If you want a Cobol, let me know.
Update: The product referred to as CIS Cobol is also knows as Micro Focus Cobol. CIS Cobol was the initial primary product of Micro Focus, who subsequently produced various other software products as well. Some sources hint that MS Cobol was a licenced version of the Micro Focus product, but I'm not certain of this, however I've just seen a document on the web referring to details of the syntax of MS Cobol that carries a reference to Micro Focus licence at the bottom. NB, the vast part of the specification for Cobol was part of the ANSI standard, which would have been followed fairly closely by actual compiler producers. However, there certainly were differences between the various compilers.
Update2: I've been digging into this further, for my own benefit as well. I'm now pretty sure that there is no connection between CIS/Micro Focus Cobol and the MS product, although they may well be pretty similar in scope and sophistication.
Note that Micro Focus is a current/active UK company (it appears) and they may well still sell their current Cobol product, and there is evidence that they are inclined to protect their copyright via legal action. MicroSoft, on the other hand, seem to have 'abandoned' their CP/M systems, which are openly available for download via the web.
The MS-Cobol package is fully compatible with MS's Fortan and the M80 Assembler/linker package, so modules from all three can be linked together.
The bits I have for Cobol v.4.65 do not include any 'installation' for any terminal type, however there is code provided (as .MAC and .REL) for various terminal types, including suitable for the Amstrad PCW, which could be linked in with any system.
The software I have did not include any documentation, however I have traced and downloaded a manual file (150+ pages) of pretty complete documentation including language reference, user guide, and full details of using the associated packages (Fortran, M80, etc) in conjunction with Cobol.
If you want a 'serious' Cobol, and the CIS Cobol is not available, I'd suggest that the MS variant will be OK.
