Fair enough, Corion ...

I have verified the correct value for $lemma by printing it in the subroutine, so I think it should be OK.

The file lexicon contains many - i.e.: MANY - entries of the format ^\w+\:=($attribute:$value,)+$attribute:$value; where $attribute and $value are lexical attributes of a given lemma (essentially a 'word' ... whatever that exactly may be).

As I mentioned in my post, the matching works fine when the entire egrep ... command is executed from the shell so I think the problem does not originate from difficulties to match the regex.

Of course, what is being matched may of course differ between the two invocations based on potentially different results of string interpolation ...

Well, as you still keep the value of $lemma hidden, most likely because the lives of uncounted children depend on it, I can't help you much further. You can help us to help you by providing a self-contained script that reproduces the problem, for example by including relevant parts of the lexicon data in a DATA section.

A typical line from lexicon:

_DATA_

tragen:=[base:tragen,cat:VVINF,stress:none,perfect:haben,sem_val:ag_th
+,valence:a,avz:allowed,extravalence:pdcis,extraobjp:zu];

_END_

A typical lemma value: $lemma = "tragen";
