Pascal Jump Instructions

Control Strucutres - Module 3

2. Linear sequences and non-linear sequences

Until now I've only teached you how to program software that has a linear sequence to it, there are no conditions, the user experience will always be the same. 

Jump Instructions

Control Structures

Subroutines

When you use any of these you are creating a non linear sequence of events.

2.1. Jump Instructions

Instruction 1;

Instruction 2;

goto k

instruction 4;

instruction 5;

k;

instruction k1;

instruction k2;

Consider the program above, when the program reaches the code goto k it would jump to k ignoring instructions 4 and 5.

Jump instructions were used in the past, before languages like Pascal or C (structured programming languages) existed, they were substituted, we now use Control Structures.
