Hi Ozo,


I copy paste the code and it produce the below error

C:\Expert-Exchange\perl>perl -F: -alne 'BEGIN{@h=qw(Subject username Date messa
e);$"=",";print "@h"}$h{$F[0]}=$F[1]or$h{Subject}=$F[0];print "@h{@h}"if /messa
e:/' <<ENDINPUT
Can't find string terminator "'" anywhere before EOF at -e line 1.

C:\Expert-Exchange\perl> <<ENDINPUT
<< was unexpected at this time.
