Counts the amount of stack data (number of words) in the specified stack. Output required
TB
D
Reads the data from the specified data element in the stack. The offset
value indicates the location of the desired data element (how many data
elements before the current pointer position).
TB
C
D
Writes the source data to the specified data element in the stack (overwrit-
ing the existing data). The offset value indicates the location of the desired
data element (how many data elements before the current pointer posi-
TB
tion).
C
S
Inserts the source data at the specified location in the stack and shifts the
rest of the data in the stack downward. The offset value indicates the loca-
tion of the insertion point (how many data elements before the current
TB
pointer position).
C
S
Deletes the data element at the specified location in the stack and shifts
the rest of the data in the stack upward. The offset value indicates the
location of the deletion point (how many data elements before the current
TB
pointer position).
