A,B,C Correct answer
Explanation

IDMS location modes determine where records are stored: CALC uses a hash algorithm based on a key, VIA places records near their owner in a set, and DIRECT specifies an exact database address. INDEX is not a valid location mode; it's a relational concept for indexed access, not a storage mode in IDMS.
