COBCH1679 PIC N (USAGE DISPLAY-1 or no USAGE) only allowed with runtime-encoding set to OEM
A data item in the source code has been specified as PIC N with USAGE DISPLAY-1, or with no USAGE specified, but the RUNTIME-ENCODING Compiler directive is set incorrectly.
If your source code contains such data items, RUNTIME-ENCODING"OEM" must be in effect, either implicitly, or by use of the RUNTIME-ENCODING"OEM" Compiler directive.
