2 Memory is to be loaded from ROM' or PROM.
3 Nonstandard control information is to be stored on the
Standard Control Information Cassette. (Refer to
paragraph 7.6.1)
Value that specifies whether ROM or PROM bit strings are
to be compared to bit strings in the memory data configuration.
The value is 0 if no comparison is to be made and I if a
comparison is to be made. The strings specified by mapping
parameters and bit string width are compared. If .a comparison
fails, the unmatched bit strings and their addresses are to be
displayed.
Parameter default values:
If ,a toggle parameter is not specified, the value specified by a previous TS subcommand or the
default value when the PROM Programmer overlay was loaded is used. The default values set up
when the PROM Programmer is loaded are the following:

Description: The toggle parameters specify the action to be taken when the GO subcommand is
entered. If the memory display toggle is set, the memory region specified by the ,memory
bounds, bit string width, and the mapping parameters lsdisphlyedin the following forinat.
Mxxxx.yy=zz
where
xxxx = memory byte address
yy :: displacement of startofbiLstring within memory byte (0 ...;;. yy ...;; 7)
zz = right justified bit string (displayed in hexadecimal)
A maximum of four entries may be displayed per line.
If the PROM display toggle is set, the PROM or ROM region specified by the PROM/ROM
bounds, bit string width, and the mapping parailleters is displayed in the following format.
Raaaa.bb=cc
where
aaaa = PROM/ROM word address
bb = displacement of start of bit string within PROM/ROM word
cc = right justified bit string (displayed as hexadecimal)
A maximum of four entries may be displayed per line.
