"Painting yourself into a corner" dept.: size of CODE RUL

I’m embarrassed to admit I’ve forgotten the macro command to increase the
number of entries in the recently-used list.  I’ve set other options
(initial size, etc.) but it looks like I never added this one to my startup
macro.

Have a laugh on me: CODE (V5R1) partially installed on my XP laptop (it
crashed on the 3rd CD; I assume I’m doing the manual install incorrectly).
Consequently, my Help is not there.  Help on my non-standard version of
WDSCi doesn’t work, and I can’t seem to google an answer.

Thanks,
Reeve
