in thread shift doesnt shift

$@ is empty. Im just using the name of the command line arg to read in a file of data. Replacing || with or didnt work. Like i said, the same code works in a different script. What else could cause a shift to die?

TIA. Joe.

    We need to see more code.

    You wrote: X or Y
    1) Y is evaluated when X is false
    2) X is empty (aka undef, aka false)
    1+2=3) Therefore Y (the die) is performed.

    So, what is the problem here? It is doing exactly what you told it to. If you want it to die on some other condition than the shift giving 0/undef/''/etc, then you need to specify that condition in your code.

    Try specifying what to shift: $var = shift @array to ensure you're shifting the right array.
