X 4.2.22 APPLY WRITE-ONLY Clause

X >_Workstation_> Under AIX, OS/2, and Windows, the APPLY WRITE-ONLY clause
X is not supported for line sequential files. It is treated as a comment
X for sequential, relative and indexed files. <_Workstation_<

X The APPLY WRITE-ONLY clause optimizes buffer and device space allocation
X for files that have standard sequential organization, have variable-length
X records, and are blocked. If you specify this phrase, the buffer is
X truncated only when the space available in the buffer is smaller than the
X size of the next record. Otherwise, the buffer is truncated when the
X space remaining in the buffer is smaller than the maximum record size for
X the file.

X APPLY WRITE-ONLY is effective only for QSAM files.

X file-name-2

X Each file must have standard sequential organization.

X APPLY WRITE-ONLY clauses must agree among corresponding external file
X description entries. For an alternate method of achieving the APPLY
X WRITE-ONLY results, see the description of the AWO compiler option in the
X IBM COBOL Programming Guide for your platform.
