Exit Statement
The
exit
statement allows you to break out of a routine (function or procedure). It passes the control to the first
statement following the routine call.
Here is a simple example:
sub procedure Proc1()
dim error as byte
... ‘ we’re doing something here
if error = TRUE then
exit
end if
... ‘ some code, which won’t be executed if error is true
end sub
Note: If breaking out of a function, return value will be the value of the local variable
result
at the moment of exit.
Return Statement
The return statement causes execution to leave the current subroutine and resume at the point in the code immediately
after where the subroutine was called. It’s mainly intended to be used with gosub statement.
Return statement suffers from the same sort of readability problems as the GOTO statement and like goto, the use of
return statement is generally discouraged.
Here is a simple example:
sub procedure Proc1()
dim error as byte
... ‘ we’re doing something here
if error = TRUE then
return
end if
... ‘ some code, which won’t be executed if error is true
end sub
Note: Return statements performs the same as exit statement except in functions. If breaking out of a function with
return statement, return value will not be specified. In such cases exit statement should be used.
Goto Statement
Use the
goto
statement to unconditionally jump to a local label — for more information, refer to Labels. The syntax of
the
goto
statement is:
goto label_name
This will transfer control to the location of a local label specified by
label_name
. The
goto
line can come before or
after the label.
