That errors seems to be quieted. THank you. Now, there is this
114: foreach( sort( keys( %freqidx ) ) ) {
115: print( "$_|" );
116: print( "$_|" ) foreach( @{$freqidx{$_}} );
117: print( "\n" );
118: }
I get the error:
Use of uninitialized value at ../20020128/pasummary.pl line 114.
Use of uninitialized value at ../20020128/pasummary.pl line 114.
I understand this also may be because I have warnings on, but I am also
trying to understand why line 114 is flagged?

Looks like it. I ran
perl -e '$i = 1; $j = undef; print $i + $j, "\n"'
and got
1
then
perl -we '$i = 1; $j = undef; print $i + $j, "\n"'
and got
Use of uninitialized value in addition (+) at -e line 1.
1
and finally
perl -we '$i = 1; $j = undef; no warnings; print $i + $j, "\n"'
and got
1
