DO.LIT / MDO.LIT 2.1(124) and SUBMIT.LIT 3.1(150) now support a new kind of command line argument, ++fspec, which gets replaced by the first line of the corresponding file. For example, if the file MYDATA:C.TXT starts with "THIS DATA", then the DO file command line:
DOTEST A B ++MYDATA:C.TXT
would expand to:
DOTEST A B <THIS DATA>
The <brackets> are employed when the line contains embedded spaces so that the entire line is treated as a single DO file or SUBMIT argument.
