Indexing a recordtype

Question

Hi All, 
 
 I have a scenario where i am getting details in a recordtype which is multiple. 
 Now i have to subsitute the record field value at a specific index of a recordtyep in interface. 
 Is that possible as i am not seeing any option to index it.

"index" means "position within an array" despite the common confusion around here caused by the "index()" function also being able to fetch a named property of a data type, meaning a lot of folks conflate the two things falsely. 
 However from the available context, I assume OP here is after the ability to index into a specific position in an array (true to the actual definition of "index"), which of course can be done both with the "index()" function as well as manually specifying an index in square brackets (local!myRecord[1], etc, which will work as long as the given number is guaranteed to exist in the given array lest it throw an error message).
