Differences:
None
See Also: Integer0Index, Integer1Index, IntegerMinus1Index
Example:
When the second argument of the
push_shift
function is positive, the shift is to the left.
So, if m is the EStackIndex at the bolded tag in the string “goodbye” as follows
0 g o o d b y e 0
STR_DATA_TAG
then
push_shift (m, Integer2Index);
pushes the left shifted string “odbye ” onto the estack such that
top_estack
points to the
bolded tag as follows.
0 o d b y e
ï ï
0
STR_DATA_TAG
