Transparent data support (SCS data stream)

The Transparent (TRN) control in SCS data streams identifies the start of a transparent data stream. NetSpool supports transparent data by including TRN controls and transparent data in line data output. NetSpool increases the output column and line position by the number of bytes of transparent data, as specified in a TRN control.

NetSpool provides two installation exits that let the administrator customize the processing of transparent data for all or selected printer names:

• The Beginning of File exit (APIPPTD1) adds transparent data to the beginning of a data set.
• The Transparent Data Control exit (APIPPTD2) inspects, changes, or deletes transparent data whenever it occurs in the data stream.
