SPF/PC

SPF/PC is an MS-DOS-based text editor and file manager designed to have an interface that was familiar to those using mainframe SPF and ISPF.
Later Microsoft Windows-based versions were named SPF/SE and SPF/SE 365. A version for OS/2 named SPF/2 was also offered. SPF/SE and SPF/SE 365 were released as freeware in 2022 after the death of Tim Tetiva, the author of SPF/PC and SPF/SE.

Similar to IBM's mainframe based ISPF and is able to edit ASCII and EBCDIC text file as a complete integrated applications development environment. Typically used for editing source code, invoking compilers, linkers, and debuggers, in a variety of programming languages, such as COBOL, Fortran, and C++.
64-bit Windows can't run SPF/PC, but it can still be used on 32-bit Windows.

Macro/Scripting Language

All versions of SPF have the ability to call any interpreter from within the editor allowing text processing and OS command calls. SPF/SE does not have the REXX interface that SPF/PC had.
