NAME

       fcasplit - tool to split source code into separate per-routine files

SYNOPSIS

       fcasplit [ -f  nmft ] [ -c  nmcc ] [ -a  nmas ] [-noh] [-log]
                [ +fo incf ] [ +co incc ] [ +ao incs ]
                [ -fo optf ] [ -co optc ] [ -ao opts ] file.ext

       fcasplit file.ext [ fca_n ] [ optf [ optc [ opts
                                   [ nmft [ nmcc [ nmas ]]]]]]

DESCRIPTION

       fcasplit, used with a command line of either form shown above, splits file file.ext having
       a mixture of FORTRAN / C / assembler routines into separate files n.f or n.c or  n.s,  "n"
       being  the name of each routine, creating at the same time a shell script file.shfca and a
       Make file file.mkfca  either of which can be used to compile  all  routines  individually.
       All  new files are generated in the current directory, even if the original file.ext is in
       a different location.

       NOTE that the program does not work on source code written  without  having  it  in  mind,
       since  fcasplit  looks for special identifying lines in comments of the source code in the
       original file, as noted below.  It is able to operate, for instance, on source code output
       by nypatchy.

       Defaults  are  defined  in fcasplit for the names by which the compilers are called in the
       generated shell script and Makefile; with the -f, -c, -a options they  could  be  changed.
       In  Debian  GNU/Linux, these defaults are gcc for the C compiler, gfortran for the FORTRAN
       compiler, and as for the assembler.

       Defaults are also defined for the options with which they are called; with the  -fo,  -co,
       -ao  options  they  can  be  re-defined;  with  the  +fo,  +co,  +ao  options  they can be
       incremented.  In Debian GNU/Linux, these defaults are "-c -g -O2" for the C compiler,  "-c
       -g  -O2  -fno-automatic"  for  the  FORTRAN  compiler,  and  ""  (i.e.,  no flags) for the
       assembler.

       To be backward compatible these options can also be specified by the positional parameters
       after the file-name (as in the second form of the command shown above).

       If  the   -noh  option is given (or if the first parameter after the file-name is "fca_n")
       the identifying header line of each routine is not written out.  If  the  -log  option  is
       given the name of each routine is printed on standard output.

FILE FORMAT

       Each routine in the original file file.ext must start with an identifying line:
         "CDECK  ID>, "      in cols.  1-12  for FORTRAN
         "/*DECK ID>, "      in cols.  1-12  for C
         ";DECK  ID>, "      in cols.  1-12  for assembler
          "DECK  ID>, "      in cols.  2-12  or
           "DECK ID>, "      in cols.  3-12  for anything else
                     "name"  in cols. 13-40  gives the name

       In  the  last  two  cases,  or  if "name" contains an extension,  the file created will be
       "name" without extension .f, .c or .s added to it and without an entry into the script.

       A trailing blank terminates the name, symbol . followed by blank also terminates,  symbols
       ; < # !   all terminate, symbol   */        also  terminates.
