NOTEMacro
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.
FEOVD Macro
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.
