CICS VSAM Transparency for z/OS, Version 1.2


BIT2CHAR

This generic exit converts bits in a binary string to DB2® character data. Each bit becomes a byte. There are no parameters required.

The exit handles input field sizes of 1, 2, 3, or 4 bytes. The output DB2 columns can be 1-byte columns, or 8, 18, 32, or 64 bytes. If the output is 1-byte columns they must be adjacent in the DB2 table. For example:
VSAM Field DB2 Row
8 bits

Either 8 x 1-byte columns
Or 2 x 4-byte columns
Or 1 x 8-byte column

32 bits

Either 32 x 1-byte columns
Or 4 x 8-byte columns
Or 1 x 32-byte column
