The Rexx interpretive language was developed for IBM mainframes. It has gained popularity among Amigoids, and to a lesser extent AIX and OS/2 adherents.
I just built this. It seems to work if I put the following in my
setenv REXXIMC /nyx/projects/pgilmart/src/rexx/source
setenv REXXPATH $REXXIMC
then execute $REXXPATH/rexx script-file-name.
Some documentation files are in the $REXXIMC directory.
