Abstract: IFTRAN is an extension of the basic set of instructions
to the FORTRAN programming language. The addition of
four simple types of clauses (IF, DO-UNTIL, WHILE, and
FOR) to FORTRAN allows the writing of structured
programs. Features of IFTRAN include OR IF and ELSE
subclauses, loop exits on logical conditions, multiple
statements on a single line, inline comments, optional
pass-through of full-line comments to the output FORTRAN
file, listing control, and "PRETTY-printed"
listings. IFTRAN avoids much of the unused richness of
most structured FORTRAN compilers in favor of quick
translation of an easily learnable and practical set of
extensions.
 
Notes: Should run under any RSX emulator incorporating features
of RSX-11M V3.2.
 
Restrictions: Bootstrap precompiler does not produce as extensive
diagnostics as the IFTRAN precompiler.
