CALL : Unconditional Call:-
This instruction is utilized to call a subroutine from a basic program. In case of assembly language programming, the term procedure is utilized interchangeably with subroutine. The address of the procedure might be specified indirectly or directly depending upon the addressing mode. Again there are two types of procedures depending on whether it is available in the similar segment (Near CALL, for example ± 32K displacement) or in another segment (Far CALL, i.e. anywhere outside the segment). The modes for them are respectively known as intra segment and inter segment addressing modes. This instruction comes under the unconditional branch instructions and may be explain as shown with the coding formats. On the execution, this instruction stores the incremented IP (for example address of the next instruction) and register CS onto the stack along with the flags and loads the registers CS and register IP, respectively, with the segment and offset addresses of the process to be called.
