error -- A utility to merge compiler error messages with the Fortran source file. (This utility is included if you do a developer install, rather than an end user install of Solaris; it is also included if you install the SUNWbtool package.)
-Xlist -- A compiler option to check across routines for consistency of arguments, COMMON blocks, and so on.
