See Syntax, linkage and programming considerations for details about how to call BCPii services in the various programming languages.

The microcode level that supports the command service call (HWICMD) of BCPii is required to be installed on the target CPC. See the HWI_CMD_NOT_SUPPORT_WARNING return code in HWICONN — Establish a BCPii connection for more information.
