SPF/PC

SPF/PC was an MS/DOS-based text editor and file manager designed to have an interface that was familiar to those using mainframe SPF and ISPF.[1]

The name was still in use 1990.[2]. Later Windows-based versions were named SPF/SE and SPF/SE 365.[3]

Overview

SPF/PC[4] was introduced by and successors sold by Command Technology Corporation. Similar to IBM's mainframe based ISPF and is able to edit ASCII and EBCDIC text file as a complete integrated applications development environment (IDE). 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 (e.g. XP or Windows-7 in XP Mode).[5]

Macro/Scripting Language

SPF/SE 365 uses a "C" like macro/scripting language.

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