The initial implementation of Unicode will not allow passed arguments to be UNICODE Alpha fields or NATIONAL Alpha fields. A runtime error should occur if a UNICODE Alpha value argument is passed to a CALL statement.
This decision will break any applications which happen to use a TEMP field to pass arguments to a CALL statement.
BUGS
Does not appear to test for Unicode or National fields, so it allows them to be passed. Tested by passing TEMP 80 to RT_SLCT_AP.
