READER RDR PRINTER PRT PURCH PCB indicates that reader files are to be changed.
indicates that printer files are te be changed.
indicates that punch files are to be changed. CLASS c1 designates an existing class. "c1" is alphameric field from A to Z, 0 to 9 or *.
a one-character
spoolid is spoolid number of the file that is to be changed. Each
file-has a unique spoolid.
ALL changes all files belonging to the user. CLASS c2 designates the new class of the file. HOLD prevents the printing, punching, or reading of a file by putting it in a user HOLD status until released by the ROHOLD operand. ROHOLD releases the specified spool file currently held by the user HOLD status.
DIST distcode
changes the distribution code of the file. "distcode" is a
one to eight character alpha.eric identification that appears
on the output separator of printer or punch output instead of
the identification specified in the Vft/370 directory. The
distribution code is changed for this file only, and does not
affect other files nor cbange the nermal user code. SYS prevents the printing or punching of the file by putting it in
a system hold status until released by using NOSYS. RAME releases the specified spool file currently being held by a
system hold status.
Note: 1 system hold has no effect on the processing of reader files. {
fn [ftl} dsname changes the name of the file. For CftS files, the specified
filenaae (and, optionally, filetype) becoae the new file
identification. For a non-CftS file, the specified dsnaae (a 1
to 24-character field) becomes the new file identification.
Note: If the NAftE function is selected and only fn is specified, ft is set to blanks. The dsnaae specification
allows a user to specify a file naae suitable for OS such as SYS1.SYSLIB.ftYftAC. FLASH name nn
specifies the flashing status of the file. The name identifies a foras overlay sheet contained in the 3800 printer. Na.e may be varied from one-to-four characters. The number nn, specifies the number of copies to be flashed. This
flash count may range from 00 to 99. A flash count of zero is
the default, which indicates flashing is not desired.

CHARS name Note: The FLASH name must match the FLASH name specified by operator in the START unless the flash count
is zero, in which case the file match is found by class of
file only.
is the name of the character arrangement table used for
printing the file. Name may be from one-to-four characters in
length. If a character arrangement table is not specified for
a file, the default table used for the separator page on the
selected printer will be used to print the file.l MODIFY name is the name of the copy modification module used for printing
the file. Name may be from one-to-four characters in length.
If not specified, copy modification will not be used for
printing the file.l FCB name is the name of the forms control buffer used for printing the
file. Name may be from one-to-four characters in length, or unique numbers 6, 8, or 12. These specifications mean:
print the entire spool file at 6, 8, or 12 lines per inch,
regardless of the size of the paper that is currently loaded. Use of the unique numbers will never cause an FCB-foras mismatch. If not specified, the value specified for the
separator page in the START command is used.l COpy [*] nn COpy nn
alters the number of copies for the file. The value of nn (number of copies) must be a number from 1 through 99. For nn
less than ten, the leading zero is optional. When the COpy parameter includes an asterisk, the file is transmitted to the 3800 printer only once. The 3800 performs the duplication
internally one page at a time. (For example, if COPY*3 is
specified, the page numbers are copied as 111 222 333 ••• ). Otherwise, the file is transmitted once for each copy desired,
with YM/370 indicating the copy number to the 3800. FILES CHANGED is the response to the user who issued the CHANGE command. This response is suppressed if the virtual machine user has
issued the SET IMSG OFF command. The system operator monitoring
the RSCS virtual machine for his installation should not specify
this option because information messages are required for
accurate monitoring of RSCS system activity. Depending upon the options chosen and the combinations
used, the actual "changing" of some files may not have occurred
because they had the new class prior to issuing the CHANGE com.and. The response is an indication of the number of
referenced files. lA specification of NULL will nullify any previous setting.
