Goto statements

When using goto statements, the following must be kept in mind:

1. The jump label must be defined in the same block as the Goto statement.
2. Jumping from outside a loop to the inside of a loop or vice versa can have strange effects.
3. To be able to use the Goto statement, the -Sg compiler switch must be used.

Goto statements are considered bad practice and should be avoided as much as possible. It is always possible to replace a goto statement by a construction that doesn’t need a goto, although this construction may not be as clear as a goto statement. For instance, the following is an allowed goto statement:

 label
   jumpto;
 ...
 Jumpto :
   Statement;
 ...
 Goto jumpto;
 ...
