RE: CPF4737 Error on window subfile

["Brown, Stephen GRNRC" <Stephen.Brown@xxxxxxxxx>]

I have some READC processing that doesn't get executed 9in this
instance), a write to a function key format followed by a EXFMT to the
subfile window. Do you think it could be the write to te function key
format that may be causing the error.

Cheers

Is it possible you are using the WRITE opcode instead of the EXFMT
opcode?
