EXIT [number]
The EXIT
command is used to stop execution of a specific block of code
and transfer control of the program to the first statement following that block.
It is often used inside FOR…NEXT
, WHILE…WEND
, or DO…LOOP
loops
to terminate the loop prematurely when a certain condition is met. The optional parameter
number
specifies the number of inner blocks you want to exit. If missing,
the implicit value is 1.
The command is useful to exit when an error or unexpected condition occurs, and it
can be used to end the code block and handle the error appropriately. In some cases,
using EXIT
can make your code more efficient by avoiding executing unnecessary
statements. EXIT
allows you to create more complex control flows and make dynamic decisions
during program execution. Excessive use of EXIT
, however,
can make your code more difficult to read and maintain.
