ICP219I FUNCTION STATEMENT FOR PCHID xxx MISSING REQUIRED VF=

xxx

Explanation
You specified the FUNCTION statement
with a PCHID keyword value of xxx but did not specify the VF
keyword. Some function types (TYPE keyword on FUNCTION statement)
require the VF keyword on some CPCs. See Table 1 to
determine which function types require the VF keyword on which CPCs.

System action
IOCP continues to validate and check the syntax
of the remaining statements. However, it does not generate an IOCDS
and it does not produce configuration reports.

Programmer response
Correct and re-run IOCP.
