How do we help people like the OP learn and develop problem solving
skills? . . . MSG instead of RCVMSG . . . and see if they can figure
it out?
I like to point out to newbies to try on the command line . . . GO
CMDMSG or GO CMDMSGF . . . play with those panels
Then with F4 prompting for the commands, and F1 reading of the help
text, newbies will pick up a lot of information - -
some information will help with the immediate problem, and some might
not be helpful until another day.
It is usually a lot easier than going through the books/PDFs.
