I am having trouble using DCL qualifiers which take a value.  In particular,
if the value is an expression, I am not able to get DCL to evaluate the
expression.  What am I doing wrong?  (VMS version 4.4).

Here is the offending DCL:


$ module = "2" + "2"
$ library /extract='module'      fortune.tlb  ! this works
$
$ library /extract="2"+"2"       fortune.tlb
%DCL-W-PARMDEL, invalid parameter delimiter - check use of special characters
$
$ library /extract=("2"+"2")     fortune.tlb
%DCL-W-NOPAREN, value improperly delimited - supply parenthesis
$
$ library /extract=(("2")+("2")) fortune.tlb
%DCL-W-VALREQ, missing qualifier or keyword value - supply all required values
