BSELECT and BDELETE commands
Interspersed blocks within one offline report or file may be either
selected for or deleted from printing by use of the BDELETE and
BSELECT commands.
TEST—BSELECT and BDELETE commands
These commands can also be used selectively to delete specialized
blocks, for example, control blocks and unsupported labels, that are
on the data tape but are not to be printed. Syntax for the TEST
parameter of BSELECT and BDELETE commands is as follows.
TEST
For online jobs, this parameter defines test expression for selecting
blocks for printing.

Options Table 7-14 lists the parameter option(s) and definition(s).
Points to note
Note the following when using the BSELECT and BDELETE
commands:
• It is important to note that block selection or block deletion is
performed before the extraction of the records from the block. If
a block is deleted from or not selected for printing, none of the
records contained within that block are processed or are
available for any other logical processing functions.
• If a block does not match the same format as the normal blocks,
it can be deleted and thus not cause a processing error. For
example, a control block in a fixed blocked file may cause a
processing error unless it is first deleted.
• When defining TABLE CONSTANTS or CHANGE parameters,
offsets to subfields of a block specify in bytes, relative to zero
from the start of block to the beginning of subfield.
