NAME

asa - interpret ASA/FORTRAN carriage-controls

SYNOPSIS

asa [filename ...]

DESCRIPTION

    Traditional FORTRAN programs put carriage-control characters in the first columns of their output, which were interpreted by older lineprinters according to the ASA vertical format control standard. (ASA was the American Standards Association -- now ANSI.)

    Under this standard, the first character of each printable record (line) determines vertical spacing, as follows:

      blank carriage return 0 two carriage returns 1 Formfeed + overprint - three carriage returns (IBM extension)

    All other characters are discarded, and empty lines behave as though they have a leading blank.

    asa interprets these characters.

EXIT VALUES

    0 normal exit

    1 inability to write on stdout or to read an input file

    2 bad argument

    Exit status values chosen from MKS toolkit.

BUGS

Currently, asa just looks at the readability of its input files at startup time. It should really do it a file at a time, but that makes the code look gross.

The carriage-control '-' is an IBM extension. Perhaps the default should ignore it and there should be a '-i' option to interpret it.
