Search Order
When RexxAddMacro loads a REXX procedure into the macrospace, the position
in the external function search order is specified. The REXX procedure may
be placed before all other forms of external function or after all other
external functions.
RXMACRO_SEARCH_BEFORE
The REXX interpreter locates
a function registered with RXMACRO_SEARCH_BEFORE before any registered functions
or external REXX files.
RXMACRO_SEARCH_AFTER
The
REXX interpreter locates a function registered with RXMACRO_SEARCH_AFTER
after any registered functions or external REXX files.
