&ZOSCHK

Indicates whether support is enabled in your product region for a specified operating system (or family of operating systems) or capability.

&ZOSCHK { ANY | ALL } name [ name ... ]

&ZOSCHK is a built-in function and must be used to the right of an assignment statement.

The result is Boolean (0 or 1):

0 means that the test failed.
1 means that the test succeeded.

Operands:

{ ANY | ALL }

This operand is mandatory. Specifying ANY means that, if any of the following tests is true, then the result is true (1 is returned).

Specifying ALL means that all of the following tests must be true for the result to be true.

name [ name ... ]

Each name that you specify here indicates an operating system (or family of operating systems) or capability that you want to test for.

The value of this field is any of the following:

GENOS

Notes:

The result is boolean (0 or 1):

0 means that the test failed.
1 means that the test succeeded. The remaining operands (at least one; as many as desired) identify a specific operating system or capability to test for. If an unrecognized name is used, then the test is treated as false.

Standard NCL function semantics apply. This function is used only on the right of an assignment statement.

This function returns 0 or 1, not YES or NO.

Examples: &ZOSCHK

&RESULT = &ZOSCHK ANY GENOS MSP
&RESULT = &ZOSCHK ALL IBM VM
