Hi,

this is probably really simple.
I am returning a numeric value from a database and want to trap it if it is null. So what i do at the moment is:

if ($id eq undef){
   ###deal with id
}else{
   ###deal with not undef id
}

What that does, works however it keeps throwing 'Use of uninitialised values in string eq' warnings, and i would like to be able to get rid of them, using an undef safe idea.

Any ideas?

Thanks -- Joe.
