Explicitly defined calls (using the CALL macro or the commands described in “Using the External Name in a Call” below) are autoresolved at verification. Otherwise, decisions for external calls need to be resolved manually.
The following Assembler statements prepare the value of the register with an external name or memory address to which a subsequent call may be resolved.
| Example | Type | External in |
|---|---|---|
L reg, =A(external) |
command | Reg |
L reg, =V(external) |
command | reg |
LOAD EP=external |
system macro | register 0 |
LOAD EP=name, LOADPT=external |
system macro | register 0 |
name DC =V(external) L reg, name |
command | reg |
