Using the CEELOAD macro

CEELOAD is used to dynamically load a Language Environment-conforming routine. It does not create a nested enclave, so the target of CEELOAD must be a subroutine.

Some restrictions apply when using CEELOAD to call, fetch, or dynamic load:

You cannot fetch or dynamically call a routine that has been fetched by or dynamically called by another language, or has been dynamically loaded by CEELOAD.
You cannot dynamically load a routine with CEELOAD that has already been dynamically loaded by CEELOAD, or has been fetched or dynamically called by another language.
You cannot dynamically load a routine with CEELOAD that has been compiled XPLINK.
The loading of a DFSMS program object with Deferred Load Classes is not supported by CEELOAD.

The syntax of CEELOAD is described in z/OS Language Environment Programming Guide.

While CEELOAD supports dynamic loading, in order to provide for loading and deleting a module, the CEEFETCH and CEERELES macros should be used.
