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.

DCP Use the DCP com.and to display the contents of real storage locations at
the terminal. In attached processor system configurations, the values
of PSA for the main and the attached processor can also be disclosed.
If an invalid operand is entered, the DCP comaand terminates.
However, any previous valid operands are processed before teraination
occurs. The format of the DCP command is: DCP KLhexloc1 NLhexlocl KThexlocl NThexlocl Khexloc1 Mhexlocl Lhexloc1
Thexloc1 hexlocl o r , r , I KLhexloc 11 1 NLhexloc 11 1 MThexloc 11 I NThexloc 11 r , 1 Khexloc 11 }:

.J {. Jlbytecount I I I I L L ..J
specifies the first storage location to be If . hexloc1 is the only operand, it specifies the only storage
location to be displayed. If hexloc1 is not specified, L or T
must be specified, and the display begins with storage
location O. If hexloc1 is specified and L or T is not
specified, the display is in hexadeciaal. T specifies that an
EBCDIC translation is to be included with the hexadeciaal
display. L specifies that the display is to be in heiadeciaal only. If hexloc1 is followed by a period and .1$ not on a
fullword boundary, it is rounded down ·to the next lower
fullword.
In attached processor systems, ft specifies that the addresses
are interpreted as though the main processor generated thea.
Thus, KO refers to location 0 of the PSI of the aain processor. The N prefix specifies that the addresses be
interpreted as though the attached processor generated thea.
The absence of K or N results in the address being interpreted
as an absolute address. N is valid only if the attached
processor is operational. K is valid if the systea has been
generated for attached processors. The prefix K or I is not
meaningful for uniprocessor systeas. Section 3. CP Commands 59
