SUBMAP manual: subroutine mapping program
P.A. Berardo, B.C. Swenson · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1982
SUBMAP is FORTRAN computer program for analyzing FORTRAN source files. It identifies the names and types of routines, and the names and references for common blocks. A tree-type listing can be generated showing the hierarchy and sequence of references starting and ending with any routine. Many other analysis options exist to summarize or extract cross-reference information, extract source code for selected routines, or reorder the source file in alphabetical or call order. SUBMAP can be used interactively or in batch mode with dynamic selection of source, input, output, and save files.
