why cannot run in the proc

[jloh81]

hi,

I try to call 2 proc togather but the second proc seems cannot work like what it work without the first proc.

Below is the code:

proc comparevalue {} {
.....
}
proc writetocsv {} {
.....
}

comparevalue
writetocsv


Please advice.
Thanks

Hi

With that code and that description of the problem we can only guess.

My guess is, variable visibility is not clear for you. In which case, compare the following three code and their behavior :

[b]set[/b] foo bar
[b]proc[/b] comparevalue [teal]{}[/teal] [teal]{[/teal]
  [b]set[/b] foo NObar
[teal]}[/teal]
[b]proc[/b] writetocsv [teal]{}[/teal] [teal]{[/teal]
  [b]puts[/b] [navy]$foo[/navy]
[teal]}[/teal]
comparevalue
writetocsv

[b]set[/b] foo bar
[b]proc[/b] comparevalue [teal]{}[/teal] [teal]{[/teal]
  [b]set[/b] foo NObar
[teal]}[/teal]
[b]proc[/b] writetocsv [teal]{}[/teal] [teal]{[/teal]
[highlight]  [b]global[/b] foo[/highlight]
  [b]puts[/b] [navy]$foo[/navy]
[teal]}[/teal]
comparevalue
writetocsv

[b]set[/b] foo bar
[b]proc[/b] comparevalue [teal]{}[/teal] [teal]{[/teal]
[highlight]  [b]global[/b] foo[/highlight]
  [b]set[/b] foo NObar
[teal]}[/teal]
[b]proc[/b] writetocsv [teal]{}[/teal] [teal]{[/teal]
[highlight]  [b]global[/b] foo[/highlight]
  [b]puts[/b] [navy]$foo[/navy]
[teal]}[/teal]
comparevalue
writetocsv
