i am learning the ACSIL language and am trying to understand the why & when to use certain parameters

i have this simple function:
this FAILS
SCFloatArray opens = sc.BaseData[SC_OPEN];
SCFloatArray lasts = sc.BaseData[SC_LAST];
  
sc.Subgraph[0] = opens - lasts;

BUT this works... why do i need to add [sc.Index] to the last line for it to work, but dont need it on first 2 lines?? or why do i need it at all if AutoLoop is set to 1? thanks for an explanation


SCFloatArray opens = sc.BaseData[SC_OPEN];
SCFloatArray lasts = sc.BaseData[SC_LAST];
  
sc.Subgraph[0][sc.Index] = opens[sc.Index] - lasts[sc.Index];
