Once your program has terminated you should copy the relevant file into your logged-in drive or directory. If insufficient space is available, you should set the COBDIR environment variable to search the directory or drive on which the file is present when your program calls it.
If the error was caused by a class which could not be loaded, find out whether or not the filename for the class (listed in the Class-Control paragraph) is a separate executable file, or contained in a .dll or .lbr file. If it is a separate executable file, the resolution is as above. If it is part of a .dll or .lbr file, ensure that the containing file has been loaded with a CALL statement before sending messages to any of the classes. If the program not found is P2emgr, you need to load the GUI Class Library, with a CALL "APIGUI" statement.
