SPFPC (1984-2017) by Command Technology was originally an MSDOS/PC implementation of the IBM Main Frame ISPF text/data browser/editor and set of programmer utilities.
SPFPC is 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 ADA, ASM, BASIC, BASH, BATCH, C, C++, C#, COBOL, FORTRAN, JAVA, Pascal. Almost any programming language can be edited with SPFPC and most compilers can be called by SPFPC which makes SPFPC as close to a universal programmer editor/IDE as you can get.
SPFPC = System Productivity Facility for Personal Computers (IBM)
MSDOS, DRDOS, PCDOS, FREEDOS, DOSBOX, DOSEMU, 16bit Windows Command Box (95/98/ME/2K/NT/Vista?/7) DOSBOX and DOSEMU use FREEDOS
Windows (Vista/7/8/10) and Linux using Wine

SPFPC REXX Special Variables
RC Return code 0 = success <> 0 error occured RESULT Contains returned value from called routine SIGL Contains procedure name and line number of calling function whenever a control flow jump is made via CALL or SIGNAL.
SPFPC REXX Trace Processing
TRACE A /* TRACE ALL CLAUSES */ TRACE C /* TRACE COMMANDS */ TRACE E /* TRACE ERRORS */ TRACE F /* TRACE FAILURE */ TRACE I /* TRACE INTERMEDIATES */ TRACE L /* TRACE LABELS */ TRACE N /* TRACE NORMAL */ TRACE O /* TRACE OFF */ TRACE R /* TRACE RESULTS */ TRACE S /* TRACE SCAN */ Trace output: nn ccc DO WHILE (position <= LENGTH(filename)) Where: nn Represents the line number of the REXX statement being executed. ccc The next three characters identify the trace line as one of the following: *-* source code +++ trace message >>> result of an expression >.> value assigned to a placeholder >V> variable contents of a string >L> literal string >F> function call string >P> prefix operation string >O> operation on two terms string >C> compound variable string During interactive tracing, after each line of output the user can enter any valid REXX statement to be executed immediately enabling variables to be modified with an assignment, variables to be queried with a SAY statement and execution to be terminated by the use of an explicit EXIT statement if, say, a loop is detected. If during testing of a procedure, a loop occurs and tracing is not active, pressing Control/Break interrupts the procedure, typing exit terminates the procedure.
