array searching

[jimcanon]

Hi,

This is my first question, I appreciate any information you provide. I
want to compare the numbers after : in @jn to the numbers after job in
@job1 and @job2.


@jn =
JN.2007:555
JN.2007:8433
JN.2007 :594
JN.2007:111
JN.2007:4663
JN.2007.321
JN.2007:2221


@job1 =
job555
job572
job8433
job873
job594
job4663
job2221
job2223

@job2 =
job555
job8433
job873
job594
job4663
job2221
job2223

I want to put what is missing in @jn compared to @job1 and @job2 in
@jobMissing :

job572
job873
job2223

I want to put what is missing in @job1 and @job2 compared to @jn in
@jnMissing :
job111
job321


Thanks and Regards,
Jim

So you want to look up stuff -> look up table -> hash.


See

perldoc perlintro (Perl variable types)
