Re: XPL problem with

[Harry Binswanger hb@xxxxxxxx]

Carl,


Ooops. I sent the wrong program. The whole problem was that putting the
 later didn't work, and yet I sent the one with the 
earlier (a test). Here's the actual one with the problem. It uses s/g
555, not 55, but I don't think that matters. I tested with 55 and got the
same results. What I get is no prompt until after I hit "x."
Interestingly, I now notice that the cursor goes back to the start of
what was on the command line, without erasing it. What do you
get?

No, I'm not using DX. Nor ES 1.

Your PRompt is misplaced. Put it before the RK statement if you
want

it to display before the RK. Also, earlier in the code, you have an

extraneous PRompt that's immediately destroyed by func FF and

therefore does nothing.


Try this:

[cr|lf]{<}EX{>}[cr|lf]

-nd

Are you freezing the display (func DX) at any point? If so, use

DO FF . Also, try having the program work in eXPanded view instead

of in a formatted view. Hard to say more without a concrete
example.
