Greetings,
I had a weird one last night w/ vtcl 1.10 over Linux (RH4.2).
I made a button and put a command in it, something like this:
"if {[check_proc "Check proc test string]} {
" puts "check was ok, ent(asdf) is $ent(asdf)
")
When I tried to run the script, it gave me a compile error.
When I looked at the auto-generated code, I saw something like
this:
"... \
"-command \n
"if\ {\[check_proc\ \"Check\ proc\ test\ string\]}\ \{\n
"\ \ \ \ puts\ \"check\ was\ ok,\ ent\(asdf\)\ is\ \$ent\(asdf\)\n
"\)\n\n
When I expected:
"... \
"-command {
"if {[check_proc "Check proc test string]} {
" puts "check was ok, ent(asdf) is $ent(asdf)
")}
Note that the code that I put into the command was not enclosed by
curly-braces by vtcl.
check_proc is defined and returns zero or one. Now, the array,
ent, is globally defined, and didn't seem to be the problem. When
I removed the reference to ent, the problems didn't go away.
Ultimately, I copied another button that was working and changed
the code to match what I wanted and everything worked fine.
My question is, what went awry? Is this a 'feature' that I can
exploit in the future?
Just thought this was interesting and worth note.
