How do I repeat a function call n times?

[Harry Binswanger hb@xxxxxxxx]

After one of my XPL pgms finds and DeFines a block, I want to see as much
of that block as I can. So the program does a function DB to get the cursor
to the beginning of that block, but the display places that block-start in
the middle of the screen, not at the top, so much of the block is below,
offscreen.
To solve this problem, I thought of putting in some functions MU, but my
screen length is 43, so about 20 MUs would be required. I seem to recall
there was a way to get a function to repeat n times. If so, what is it? Or
is there a more elegant way to get the start of the DeFined block placed at
the top of the screen?

Thanks.
