Either the filename is incorrect, or the path containing the file has not been specified on either the SQLCPY or the COBCPY
Do one of the following:
Correct the filename.

Note: The preprocessor looks first in the current directory, and then down the paths specified by the SQLCPY environment variable,
and then the COBCPY environment variable.
