[gradsusr] Error opening .txt file in a grads script

[Jeff Duda]

The snippet of script code you included isn't consistent with the output
you included. I can't see from what you included what would be the cause of
the error. Do you have non-alphanumeric characters in your text file?
Otherwise I suspect you have a syntax error in your script somewhere else.
