Re: ASCII to EBCDIC translation

You could overlay a character field over your array, and check the length
there.

Thanks,

The problem with this approach is that the byte array returned is of
varying length, and I need to know the varying length, with a char I can
determine the size in rpg with the %len with the integer array this is
not possible.

Is there any way to stop this conversion when using a varying chr field?
