SUBROUTINE COMPAC(NUMBER)
*-----------------------------------------------------------------------
*
* extracts the FORTRAN field contents from the statement image.
* Modified by JJB to allow for inline comments starting with "!"
*
*--- input
*    NUMBER          number of the statement to be extracted
*    SIMA            COMMON/ALCAZA/ (contains one complete routine)
*    NLTYPE,NFLINE,NLLINE,  COMMON/STATE/
*
*--- output
*    SSTA            COMMON/ALCAZA/  FORTRAN fields 7-72 of SIMA
*    NCHST           COMMON/STATE/  last non-blank in SSTA
*                    or =0 if statement consists of comment lines only
*    NLIMA, NLREF(1..NLIMA),   /STATE/
