CSNBHMG and CSNBHMG1 provide identical functions. When choosing which service to use, consider the following:

• CSNBHMG requires the application-supplied text to reside in the caller's primary address space.
• CSNBHMG1 allows the application-supplied text to reside either in the caller's primary address space or in a data space. This can allow you to process more data with one call. For CSNBHMG1, text_id_in is an access list entry token (ALET) parameter of the data space containing the application-supplied text.
