[Info-vax] Howto can I call the undocumented "set watch/class=dir" in an own program and fetch the output in my program?

[Volker Halle]

Here is an example:

AXPVMS $ define/super sys$output xqp.txt
AXPVMS $ set watch file/class=major
AXPVMS $ dir xqp.txt
AXPVMS $ set watch file/class=nomajor
AXPVMS $ deass/super sys$output
AXPVMS $ ty xqp.txt
