C--- 8 June 1999 Chris S. modified to read a file with the first argument
C--- being a generator type
C--- added 'integer gentype'
C--- added 'Reading in a generator type' and 'read *, gentype'
C--- added 'gtype' and 'integer gtype' to 'check_gen' and 'check_errors'
C--- section 'Unpack invalid string' has been commented
C--- it creates an error
