Hopefully not trying the patience of the FTN95 Community,

One hopefully quick question about updating a %gr drawing surface
using ClearWin+, viz...

So far I have left all my winio commands in the main program,
as relegating graphic updates to subroutines always opened
up a new graphic window on top of all previous ones. I ended
up with a pile of windows instead of changing the *one* I wanted
to update.

Called from [main] everything works for the animations, but the
code is cumbersome, ponderous and unsightly.

Can someone tell me how I can get a subroutine to update a window
graphic started from [main] or another subroutine?

I hope the above is not a bother.

Best,
Ludwig

Are you using %lw to leave the window open? If not then this may be the answer.
An (often better) alternative is to use %sc and to put the drawing into a callback function.

Otherwise, can you post a small program to illustrate what you are doing?
