Regarding Script Logic

Hello Experts,

I have a doubt regarding script logic, the code is executed

*FOR %VAR%=1,2,3,4,5,6,7,8,9,10

*WHEN CATEGORY

*IS ACTUAL

*REC(FACTOR=1,CATEGORY=FORECAST,TIME=TMVL(%VAR%,%TIME_SET%))

*REC(FACTOR=1,CATEGORY=PLAN,TIME=TMVL(%VAR%,%TIME_SET%))

*ENDWHEN

*NEXT

1. In the above statement what does %var% mean or how is the value populated (is it from the input schedule ) , and does the %TIME_SET%

2.Second in the TMVL structure suppose the %var% is 3 will the record be created for 3 , 2 and 1.

thanks

Raj
