In a follow-up to RFI # 1610, we would like to know under what situations, the following code is used?
IK502 = 16 (Syntax Error in Decrypted Text)
Can this code be used for decryption failures?
With regards to your question, referencing the previous RFI 1610.
The answer would remain the same, when a functional group has been encrypted and has been corrupted, rendering it unusable.
