Using MI Instruction CALLPGMV 
Table of contents: Historically, external calls in HLLs could not take advantage of specific features at the MI level; but that changed with i 5.3 and the introduction of the CALLPGMV MI instruction. This instruction lets programmers dynamically determine both a program to be called and the argument list to the called program and reduces the time necessary to resolve program objects with system pointers. And if that isn't enough, CALLPGMV also provides a method for suppressing adopted authorities.
