Error handling

APSRCF30 detects each of the errors in the following list, and places the return code (RC) for it in register 15. The return code prints on the screen when you are using the APSRCF30 EXEC. When an error occurs, the font-conversion program might create an incomplete output file, which you should discard.

RC

One or more of the conversion character data set members required by the conversion program could not be found. The DD of the required conversion character data set is FONTB300.

20

An I/O error occurred while APSRCF30 was writing to the output data set.
