Break
The break statement can be used to terminate the execution of a while, repeat, or for loop,
skipping to the next statement after the loop. A break ends the innermost enclosing loop.
Return and break statements can only be written as the last statement of a block. If it is necessary to
return or break in the middle of a block, an explicit inner block can be used.
The output you get from these examples may vary depending on the data format settings of the
instrument.
Example: Break with while statement
local numTable = {5, 4, 3, 2, 1}
local k = table.getn(numTable)
local breakValue = 3
while k > 0 do
if numTable[k] == breakValue then
print("Going to break and k = ", k)
break
end
k = k - 1
end
if k == 0 then
print("Break value not found")
end
This example defines a break value
(breakValue) so that the break statement is
used to exit the while loop before the value of
k reaches 0.
Output:
Going to break and k = 3
Example: Break with while statement enclosed by comment delimiters
local numTable = {5, 4, 3, 2, 1}
local k = table.getn(numTable)
--local breakValue = 3
while k > 0 do
if numTable[k] == breakValue then
print("Going to break and k = ", k)
break
end
k = k - 1
end
if k == 0 then
print("Break value not found")
end
This example defines a break value
(breakValue), but the break value line is
preceded by comment delimiters so that the
break value is not assigned, and the code
reaches the value 0 to exit the while loop.
Output:
Break value not found
