I'm trying to get $read to return the first thing in a file that does not match the specified fields.
For example, say the file had:

233
ABCD
X3
G

And I wanted it to exclude 233, ABCD, how would I return the first thing that didn't include those two (233 and ABCD are in variables)? I tried using a $read(filename.txt,r,/[^233]|[^ABCD]/) do it, but it didn't seem to work :\ (I'm probably just really bad at expressions :\ )

Thanks in advance as always,
