Use the execute form of the UCBSCAN macro together with the list
form for applications that require reentrant code. The execute form
of the macro stores the parameters into the storage area defined by
the list form.
Syntax
The execute form of the COPY function of the UCBSCAN macro is written
as follows:

Parameters
The parameters are explained under the standard form of the COPY
function of the UCBSCAN macro with the following exceptions:
- ,MF=(E,list addr)
- ,MF=(E,list addr,COMPLETE)
- Specifies the execute form of the UCBSCAN macro.
The list
addr parameter specifies the address of the storage area
for the parameter list.
COMPLETE specifies that the system
is to check for required parameters and supply defaults for optional
parameters that were not specified.
