CALL (Call Near)
The CALL instruction calls a function at the specified near address. The CALL
instruction uses the (short) absolute addressing mode. The near-address
expression must resolve at link-time to an absolute address in the range h’0000
to h’1FFF. Therefore, this instruction can only be used to call functions that
reside in the near area.
See Chapter 8, System-Provided Functions, for a description of system functions
that you can use with this instruction.
The CALL instruction applies to Series 3100, 5000, and 6000 devices.
Syntax:
The CALL instruction requires a single operand to specify the near address:
CALL near_address
