Conditional only seeing last condition?

[starlight849]

I have a perl script that goes to write to a file based on whether a string contains A, B, C, or D.
The string are populated from a read in file and all letters are absolutely contained in the file and being read.
Such as this:

if (($myString eq "A") ||  ($myString eq "B") || ($myString eq "C") || ($myString eq "D"))
{
print OUTFILE "print some stuff";
}

My problem is that whichever condition is last will be written to the file. (In this case D) If I changed the last condition to A then I would only see A's in the output.

Is there something wrong with my conditional statement?

Can you show us the contents of the file and how you're assigning $myString?

You conditional could be cleaned up. Try this:

if ( $myString =~ /^[ABCD]$/ ) {
    print OUTFILE "print some stuff";
}
