An RPG II development system for CP/M originally introduced in 1981 by the Software West company, that was later ported to DOS in 1985. Unlike some of the later RPG development tools for the PC it does not mimic the System/3x environment completely for development of S/3x software on the PC but rather focuses on having compatible tools for CP/M and DOS targeted development. The company announced an RPG/400 compatible product for DOS that would be delivered in 1991 as PC RPG III but appears never to have shipped it.

Features

The original RPG II CP/M system was simply a compiler that was compatible with RPG II language as it was on the System/3. The 1983 release of the PC RPG II system is actually just the CP/M system on DOS floppy disks shipped with a Z80 based CP/M card for the IBM PC. The PC RPG system introduced in 1985 comprised of an RPG II DOS compiler that was compatible with the RPG II language as used on the System/34, support for sequential, direct or ISAM file processing, a disk based sort/merge utility and a linker supports linking the compiler's output into an executable with a runtime executive that controls the program's behaviour and can also link with assembly language routines.

Later versions added a full screen editor called Source Editor Utility (SEU) but that is a basic PC text editor with a few features helpful for RPG programming rather than an S/34-6 compatible product. The Screen Design Aid (SDA) screen painter that was added in the early 90s however has some compatibility with the S/36 screens and indeed would write and open any WORKSTN compatible file, but also offers some superset features such as colour support. Around 1990 the system started assuming System/36 rather than S/34 compatibility, utilities for conversion of EBCDIC to ASCII were added alongside other utilities that helped with migrating from an S/34-6 system such as a library conversion utility and so on, so forth.
