A Flaw

[SoloCDM]

The attached sample (it isn't the entire script) has no problems
processing as is, but when I remove the comment from "FSCREEN" *or*
"echo $MFILTER $MFILTER_ANS", it automatically skips "read MANS" and
accepts the wildcard in the case as the answer for "MFILTER_ANS".

When I remove the tabs preceding every line, then the prompt for read
works, but with "FSCREEN" *and* "echo $MFILTER $MFILTER_ANS"
uncommented nothing happens to the screen.  If I copy down the
function lines for "FSCREEN" to replace "FSCREEN", nothing happens to
the screen.

This problem can be reproduced; therefore, what is causing the
problem?
