VARS_LIMIT U16 (limits) r
VARS_LIMIT is the compile time constant that defines the absolute
maximum size of the variable table. The product must be recompiled and
redistributed to increase this absolute capacity. The combined sum of the
VARS and VARS_LOC limits must be less than or equal to the value
VARS_LIMIT.
VARS_LOC U16 (limits) rw
The VARS_LOC limit determines the maximum number of local variables
that can be defined. Local variables are explicitly defined by the LOC
command, and are implicitly defined for macro parameters.
The VARS_LOC limit must be set before any local variable is defined. The
combined sum of the VARS and VARS_LOC limits must be less than the
value VARS_LIMIT.
VARS_TABLE U16 (limits) rw
VARS_TABLE tracks the total number of entries in the variable table, which
is defined to be the sum of variables VARS plus VARS_LOC. The VARS_TABLE
size must always be less than or equal to VARS_LIMIT.
VERSION STR (misc) r
The version ID of the program, for example, "DAT XL A.00.00".
VW LPTR (win) r
The virtual address where the current virtual window is aimed.
VWO SPTR (win) r
The offset portion for the virtual address where the current virtual window
is aimed.
VWS U32 (win) r
The sid portion for the virtual address where the current virtual window is
aimed.
WIN_LENGTH U32 (io) rw *
Specifies the number of lines available on the display terminal. The
default value is #24. Values grater than or less than the actual number of
terminal lines may cause unpredictable screen output.
WIN_WIDTH U32 (io) rw *
Specifies the number of columns available on the display terminal. The
default value is #80. Modification of this value is permitted, but the value
is ignored.
X U16 (c*eg) r dm
The CM X (index) register.
ZW U32 (win) r
The real address where the Z window is aimed.
