Controlling Bypass Label Processing (BLP)
You can use File Manager to control tape label processing by your users even if your system installation parameters (JES parameters) would not allow BLP.

If your installation allows BLP usage (as specified in your JES parameters), normal open processing checks if the user has access to ICHBLP. Any user with READ access or greater can use BLP. If ICHBLP is not defined to your security product, all users can use BLP.

If your installation does not allow BLP usage (as specified in your JES parameters), then if LABEL=(,BLP) is coded on the JCL control statement, BLP is converted to NL. However, File Manager users can still use BLP subject to the following conditions:

File Manager must be running APF-authorized.
For any function other than TLB, the user must have access to FILEM.TAPE.BLP.
If ICHBLP is defined to your security product, the user must have READ access or greater to it.
In this case, if either:

LABEL=(,BLP) is coded on the JCL control statement
or

LABEL=(,NL) is coded on the JCL control statement
the user can specify LABEL=BLP on the first File Manager function that uses a tape. This means that the user wants to use bypass label processing (BLP) for the tape.

This is illustrated in Figure 7.
