WebThe variants of these instructions that transfer control to other segments are discussed in a later section of this chapter. If the model of memory organization used in a particular 80386 application does not make segments visible to applications programmers, intersegment control transfers will not be used. WebThe instructions in this category operate on strings rather about up logical or numeric values. Refer also to the portion on I/O for information about the string I/O instructions (also common as block I/O). The power of 80386 string operations derives from the following traits of the bau: A set of primitive string exercises. MOVS-- Moving String

WebThe jmp ( jump) instruction unconditionally carries control until another tip in the program. There are three forms of diese instruction: a direct jump and two indirect jumps. Diese instructions take aforementioned following application: jmp label; jmp( reg32); jmp( mem32); The first instruction is a direct jump above.
