IBM OS/390 ユーザーズマニュアル

The MVS NOTE macro is valid only for BSAM and BPAM.

NOTE returns the following information:

VSE-register 0: 00nn
VSE-register 1: CCHR
MVS-register 1: TTR0

where

nn = Unused space remaining on the track following the end of the

identified record.

 C = Cylinder number.
 H = Track number.
 T = Relative track number.
 R = Block number of that track.

The functions of the VSE FEOVD and MVS FEOV macros are the same.

Figure 38 on page 310 shows a comparison of the operands of the DTFSD and
DCB macros. Figure 39 on page 311 shows a sample of the I/O macros used
with sequential direct access files in VSE and MVS.
