An Index variable is a variable defined as a part of u r table index

While a normal variable is a variable used to store data temp..
eg:if u r defining a table(array)

as PLAN-DATA-COUNT OCCURS 10 TIMES indexed bu sub1

so sub1 will keep that count (1 to 10) something like
(sub1=1;sub1<10;sub1++)

Hi there,

Few more points...

Index variable can not be use with compute verb.
we can use only
set index-var up by 1
or
set index-var down by 1

Index variable is updated by search.
