EDIT Subcommands-SCROLL/SCROLLUP, SERIAL n is a number from 1 to 255 that specifies the number of successive
screens of data to be displayed. If an asterisk (*) is specified,
the entire file, from the current line to the end or of
the file, is displayed. If n is not specified, 1 is the default.
1. The SCROLLUP subcommand can be specified by any combination of the
truncation of SCROLL and UP; the minimum truncation is SUe 2. The number of lines shifted forward or backward depends on the
current verification setting. If the verification setting is 80 characters or less, then a scroll request displays a file in
increments equal to the number of lines that can be displayed in
the output display area of the screen. If the verification setting
is more than 80 characters, then a SCROLL request displays a file
in increments equal to half the number of lines that can be
displayed in the output area. a single SCROLL on a 3270 Kodel 2 display terminal is
the equivalent of DOWN 20 or DOWN 10, depending on the record
length, and SCROLLUP is the equivalent of UP 20 or UP 10. 3. When vou use the SCROLL or SCROLLUP subcommands to display more
than one screenful, each display is held for one minute, and the
screen status area indicates MORE •••• To hold the screen display
longer, press the Enter key. halt scrolling before all the requested screenfuls are
displayed, enter the HT Immediate command and press the Cancel key twice. U. When you begin scrolling from the top of the file, the first
screenful contains only the first seven lines. When you scroll to
the end of the file, the last screen may duplicate lines displayed
in the previous screen.
The screen displav is shifted forward or backward. SERIAL Use the SERIAL subcommand to control the serialization of records in
columns 73 through 80. The format of the SERIAL sub=ommand is:
r -, I SERial fFF ! I I r , I I ON lincrl , I ALL IlQ. I , I seq
L .J I L- -.:I 248 IBM VM/37Q eMS Command and Macro Reference
EDIT Subcommands-SERIAL OFF indicates that neither serialization numbers nor identifiers are
to be placed in columns 73-80. ON indicates that the first three characters of
be used in columns 73-75 as an identifier.
filename are to
ALL indicates that columns 73-80 are to be used for serialization
seq specifies a three-character identification to be used in columns
incr specifies the increment for the line number in columas 76-80 (or 73-80). This number also becomes the first line number. If incr
is not specified, then 10 is assumed.
1. The SERIAL subcommand is valid only for files with fixed-length, SO-character records. To renumber VSBASIC or FREEFORT files, use
the RENUM subcommand.
2. The serialization setting is ON, by default, for the following
filetypes: ASSEMBLE COBOL DIRECT FORTRAN MACRO PLI PLIOPT UPDATE UPDTxxxx 3. When serialization is in effect, records in a file are resequenced
each time a FILE, SAVE, or AUTOSAVE request is issued. If you are
using line-number editing, you must issue the subcommand:
linemode off
before issuing a FILE or SAVE subcommand if you wish the records to
be resequenced.
If you issue the SERIAL subcommand in a file with a zone column greater
than 72, the message:
is displayed, to indicate that the zone has been changed. If the zone
column is 72 or less, but the truncation column is greater than 72, the
message: TRONC SET TO 72
is displayed. Section 3. EDIT Subcommands and Macros 249
