RE: Convert hex to char (cvtch)

This is the dreaded 'B' binary data type issue.

D  hexFunctCode                  4B 0

The above does NOT define a binary field 4 bytes long.  It defines a binary
field which can hold four digits of information, which is actually a
two-byte field.  So you want to be converting a 2-byte hex field into a
4-byte character field.  Change your code as shown:


D  hexFunctCode                  4B 0
D  alp2HexBytes                  2A   OVERLAY(ds_ZDAQ0200:29)

D  alp4CharBytes  S              4A   INZ

C                   CALLP     cvtch(%ADDR(alp4CharBytes)
C                                  :%ADDR(alp2HexBytes)
C                                  :%Len(alp4CharBytes)  )
