Re: how test for empty sub-sequence?
Joe,
My code's such a mess at this point I think it would take as long to
abstract relevant snippets as to try to follow what it is I made happen. I
thank you for the offer, & if I start pulling out too much of my hair, I may
re-think & start snipping!
In general, I had made a number of stand-alone modules to make different
tasks work (pretty simple things like: edit keyed in text; save result in
variable to disk; read it; show it with original font size); then I
"integrated" the modules by turning them into includes, with global
variables to pass various info back & forth between them & to "main", and
now it mostly works except in one (?) mostly avoidable instance. The real
problem is that I'm running the unregistered Euphoria, so while I got error
messages with the small modules, I don't now that I've integrated them, so I
have to THINK about what is happening, & hope I'm mentally following my own
code correctly (no small task for me!).
The problem relates to when I try to set fontsize from info that was stored
into disk file & then read back out into a "structured"(?) variable; it
works ok when I actually DO store font size info, & crashes if I haven't,
that's why I thought I was trying to read an empty sequence.
I'll get back to you if I can't figure it out on my own. :)
