I defined a variable (only part of the uproc is shown): } elseif [cequal [crange $segment 0 2] GT1] {
set fieldList [split $segment $field_sep]
set gt1_5 [lindex $fieldList 5]
echo $gt1_5
(this returns a value)set segment [join $fieldList $field_sep]
append outbuf ${segment}r
} else if [cequal [crange $segment 0 2] PID] {
echo $gt1_5
(this returns nothing)}
The echo does not work in the PID segment area. I need to reuse the contents of $gt1_5 within the PID segment ‘elseif’ statement. I can pull a variable defined within the MSH ‘if’ statement defined earlier and use it just fine in a ‘cequal’ condition.

Is this part of some sort of iteration/looping? Can you post the full uproc?

Sorry, GT1 should have this in it:
set gt1_5 [lindex $fieldList 5]
I’ve been testing and posted a version without it. Should clear up any obvious problems.
This is weird. I can resuse any other variable defined earlier in the proc except this one. Special name?

Mike,
I usually put a set of delimiters around my echoes so that if I am echoing a null value I will know it.
Maybe the value is null.
I do something like this echo”>$var<"
Then if I have null in $var I get >< and it becomes obvious.

Mike,
I guess it is also possible you are not passing the if and thus the echo is not getting executed.

I got word from another programmer that the GT1 segment occurs after the PID segment, thus the variable was not intialized at that point. He gave me some code that loops through the segments in this case so that you can initialize the variable within a segment if the segment occurs after the segment you are in:
set gt1val “^GT1\|”
set segList $segmentList
set finx [lsearch -regexp $segList $gt1val ]
if {![cequal $finx -1]} {
set gt1 [lvarpop segList $finx]
set gt1_5 [lindex [split $gt1 $field_sep] 5]
}

Actually I wonder why you are not doing this in an Xlate.

Also, you could clean the little piece of code that was given to you by doing this:
set gt1seg [lsearch -regexp -inline $segmentlist ^GT1 ]
set gt1_5 [lindex [split $gt1seg $field_sep] 5]
The -inline will pull the entire GT1 segment instead of just it’s index. The two “set” commands at the beginning aren’t even needed.
Hope this helps…Tom

Pretty slick Tom. Works! I like less code… 😀
