ZONE Request
Format:

n1 n2
! truncol
n1 specifies the initial column of the zone of each record
which is to be scanned. The default value is column 1.
n2 specifies the terminal column of the zone of each
record which is to be scanned. If serialization is in
effect!, the default value is 71 for SYSIN,. ASP360,
COpy I' and UPDATE files and 72 for FORTRAN, PLI, SNOBOL,
AED, FLOW, MAD" AS1130, and REPS files. If
serialization is suppressed, the default value is 132
for all SCRIPT and LISTING files, and 80 for all
others, including MEMO, DATA, and EXEC.
Usaqe:
This request causes subsequent LOCATE and CHANGE requests to
apply only to the zone of the records specified by the
integer values for starting and ending columns.
The initial zone column, nl, must
final zone column, n2" and n2 must
the truncation column.
be strictly less than the
be less than or equal to
If serialization is requested by use of SERIAL and the
current zone overlaps columns 73-80, the ending zone column
is res'et to 72.
Notes.
a. If serialization is in effect for SYSIN, ASP360, COPY,
or UPDATE files, the default value of truncol (n2) is 71,
but the ZONE ending column can be set to column 72 to insert
a continuation character in a record.
b. In addition to its obvious uses in searching and
modifying fixed-format card files" the ZONE request has
utility in source program editing for adding comment fields,
adding continuation characters, and searching on the
serialization field, columns 73-80.
c. To change the limits for fixed-column requests, such as
FIND., BLANK!, and OVERLAY,. the TABSET request should be used.
For ,.!xample l • to overlay starting in column 52 of each card,
the request TABSET 1 52 should be used.
