System Debug display this register with two formats:
STATUS=%100030=(Mitroc CCG 030)
The first value is the full 16-bit integer representation of the register. The
second format shows the value of the special named bits. An uppercase
letter means the bit is on while a lowercase letters indicates the bit is off.
The segment number has various interpretations. For non-CST expansion
systems, this is an absolute segment number. For CST expansion systems,
refer to the
MPE V/E Tables Manual for details on its interpretation.
SYMPATH_UPSHIFT BOOL (misc) rw
TRUE if path specifications used by symbolic formatting should be
upshifted. This should be FALSE if a symbol file originated with a
case-sensitive language, such as C. Note that this variable affects only
those symbols entered in System Debug commands and functions, not
those in symbol files.
SYSVERSION STR (nmreg) r
The version of the operating system (as found in SYSGLOB).
This variable is currently a null string in DAT.
TERM_KEEPLOCK BOOL (io) rw
If this variable is set, the terminal semaphore is not released when the
process is resumed by Debug. The default for this variable is FALSE. If the
process dies, theterminalsemaphoreis automatically released. If the TERM
NEXT command is issued or the value of TERM_LOCKING is changed, this
variable is reset to FALSE.
This variable is available only in Debug.
