BIT^SET
BIT^SET
This procedure sets to 1 the ith bit of a bit map table in either global or extended
memory.
table input
is a pointer to the bit map table.
index input
INT:value
is the index for the bit to be set to 1 (not available). The range for this parameter is
specified by: 0 <= index < 32, 768.
BIT^TEST
This procedure tests whether the ith bit is set in a bit map table in either global or
extended memory.
result returned value
INT:value
is one of the following values:
Caution. You must not reset TSCODE-defined map bits.
CALL BIT^SET ( table !
i
,index ); !
i
INT:ref (Use for global memory reference.)
INT .EXT:ref (Use for extended memory reference.)
result := BIT^TEST ( table !
i
,index ); !
i
-1 The bit indexed by index is 1 (ON)
0 The bit indexed by index is 0 (OFF)
