When you specify the -cm command-line
option, the glfiles utility creates a file that
lists the available character mapping (charmap) files.
For each cmZ subdirectory
in $INFORMIXDIR/gls, glfiles creates
a file in the current directory that is called cmZ.txt,
where Z is the version number of the charmap object-file
format. The cmZ.txt file lists
the character mappings in alphabetical order, sorted on the name of
the GLS object charmap file.
