April 8, 1983 PARSE A Flexible Filespec Parser for FORTRAN R. W. Barnard Sandia National Laboratories Albuquerque, NM 87185 PARSE is a subroutine which makes specification of files used in a program easy, and requires a minimum of operator input. A complete description of the code is given in the magazine SEXTANT, Summer, 1983. The version given here is specifically designed for DEC machines; the version listed in SEXTANT is more "generic". This submission includes PARSE.FOR, and EXAMPL.PAR; the former is the code, and the latter is a pseudo-program illus- trating ways to use PARSE. Additionally, PARSE.FTN is a version for RSX (or VMS level-1 directories), which includes the ability to specify UIC's and version numbers. PARSE.FOR is written in FORTRAN-IV, and uses RT-11 SYSLIB routines; PARSE.FTN is written in FORTRAN-77.
