dear mumia w,
thank for your support. as you supposed the values aren't equal.
the subroutine's argument is "1". had databaserequest_noun been
interpreted in scalar context inside the if-clause, with the result
that its value is an integer and not a string as required? is this
the reason why the comparison doesn't succeed? and how can i make
sure that databaserequest_noun will be interpreted as an
array-variable?
best regards

if ((function_name($var1,$var2))[0] eq 'MyString') {

dear mumia w,
i have tested the proposal you've made the following way:
if ((databaserequest_noun($col, $table, $case) )[0] eq
$Q::lexicalentry) {
print $q->p("the entry is part of the database");
}else { print $q->p("the entry isn't part of the database");}
unfortunately it doesn't work. i don't understand the meaning of [0].
could you please explain what's about this expression?
best regards

Again, find out what databaserequest_noun() returns by assigning to a
new variable first then printing or by using Data::Dumper:
print Dumper(\databaserequest_noun($col, $table, $case));
The (function())[0] syntax puts the function call into list context so
that you can get the first array element ([0]) rather than the array
size.
print Dumper(\databaserequest_noun($col, $table, $case))
> returns $VAR1 = \1;
Let's keep it on the list.
Evidently, databaserequest_noun($col, $table, $case) does not
return 'Italy.' It returns '1', even in list context.
I have no idea what databaserequest_noun() does. I can't find
any information about it on Google. My best advice at this
point is to read the documentation (if any) for the function,
so you can be sure what the order of the arguments are (the
arguments are $col, $table and $case) and what the return
value is (in this case, '1').
Good luck.
