Calling procedure/subroutine

Here the code segment consists only one procedure. The FAR operand in
this case informs the assembler and linker that the defined procedure name is
the entry point for program execution, whereas the ENDP directive defines the
end of the procedure. A code segment however, may contain any number of
procedures, each distinguished by its own PROC and ENDP directives.
A called procedure is a section of code that performs a clearly defined
task known as subroutine which provides following benefits.
? Reduces the amount of code because a common procedure can be called
? from any number of places in the code segment. ?
? Encourage better program organization. ?
?
? Facilitates debugging of a program because defects can be more clearly
isolated. ?
?
? Helps in the ongoing maintenance of programs because procedures are
readily identified for modification. ?
A CALL to a procedure within the same code segment is NEAR CALL<. A FAR CALL
calls a procedure labeled FAR, possibly in another code segment.
