I really like the look of DT_INTS-18.bas but there are a few syntaxes I didn't understand.
In the 'Elapsed_INT-18.bas' program you use 'MOVE?CT 0, T1CON,TMR1ON'
and in 'DT_INTS-18.bas' you use 'L?GOTO _RestorePBP_H'.
I've been looking for the '?' syntax. Where can I find it? It wasn't in the MPASM User Guide (at least not mine) or the PBP Compiler book.

I'll probably make a lot of people feel smart by asking this but I like to understand what I'm using.
