need help in Perl

I am writing programmes in perl .I have wrote common functions in one program and i want to call that function in Main programme .

Please can you tell me syntax ..

Example:

Main Programme test.pl

i wrote errors1.impl and want to call in test.pl

please tell me the synatx

put the follwing line in errors1.impl
`test.pl`

Note that those are inverted commas not single quotes.

If you have a Perl script that needs to invoke another Perl function in an external Perl script, then those shell (backticks) thingys are totally irrelevant.

Use require():
