ok, then how is it done syntacticly. Wrapping the open in an
`if', I guess would be one way.
if(open(FILE,"<$file")){
do a string of things;
}else{
issue warning message;
return;
}
Above would be one test for undefinedness...
But what if for one reason or
another I wanted to just test to see if the open() had failed.
What would that sort of test look like?
