Example:
When the second argument of the
push_shift
function is negative, the shift is to the right.
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, IntegerMinus1Index);
pushes the right shifted string “ goodby” onto the estack such that
top_estack
points to the
bolded tag as follows.
0
ï
g o o d b y 0
STR_DATA_TAG
