I am trying to write a simple proc that we can use for table lookups by using arguments. I know that i can do this in an xlate but we have some feeds that dont require xlates and i dont want to make one just for a table lookup. I was thinking of making the args, just an example{SEGMENT OBR} {FIELD 15} {TABLE specimanSource} , but i am getting a little lost on where to go. any help or ideas are appreciated. thanks.
proc tpsSetTableValue { args } {

My bad, if i would have proof read it i probably would have realized that. I am not getting any error. Its pulling the value out of the field but it’s not doing anythign with it. In the screen shot i added i circled where the new value should be. There was a number there but i am trying to replace it with a description. i have echoed the value and it comes back with nothing.
Thanks.

Code:
for { set flds $fldCnt } { $flds < [expr $FieldNum + 1] } { incr flds } {
lappend fldList {}
}I think the “expr” command is redundant. Expr is implicitly called to evaluate the condition of a for loop.
Code:
set value [tbllookup $TableName $FieldVal]lset fldList $FieldNum $FieldVal
Before this code, FieldVal should probably be set to [lindex $fldList $Fieldnum]. It appears to be uninitialized.
Also, it looks like you’re putting the result of the lookup in a variable called “value”, but you aren’t doing anything with the result. On the second line you should probably replace $FieldVal with $value.
