The ICSF callable services generally follow the naming conventions outlined in the following table.

There are five exceptions where the CSFzzz names would collide and in those cases, the CSFzzz alias is CSFPzzz instead: PKDS Key Record Create (CSFPKRC), PKDS Key Record Delete (CSFPKRD), PKDS Key Record Read (CSFPKRR), PKDS Key Record Write (CSFPKRW), PKA Key Token Change (CSFPKTC),

In the following table, zzz is a 3- or 4-letter service name, such as ENC for the Encipher service or PKG for the PKA Key Generate service. Not all CSNBzzz/CSNEzzz services have ALET-qualified entry points (where certain parameters can be in a dataspace or an address space other than the caller's). See each specific service for details.
