RE: ASCII to EBCDIC translation

["Joe Pluta" <joepluta@xxxxxxxxxxxxxxxxx>]

We're going to have to get this into a FAQ, but for now there's a very
simple rule: if you define your data as type "A" in your prototype, RPG
will convert a Java byte array from ASCII to EBCDIC.  If you instead
define it as "3i 0", no conversion will occur.

This is the offender:

> d getCDR          pr         65535a   extproc(*JAVA:CGF
> d                                            :'getCDR')
> d                                     varying

In your case, I think you want to do the following:

d getCDR          pr             3i 0 extproc(*JAVA:CGF
d                                            :'getCDR')
d                                     dim(32767)

Note that the max for DIM is 32767, at least at V5R1.  Also, I haven't
exactly tried this; I've only used it to pass a byte array back and
forth as a parameter.
