Perl continue Function


Advertisements


Description

This function is a flow control statement rather than a function. If there is a continue BLOCK attached to a BLOCK (typically in a while or foreach ), it is always executed just before the conditional is about to be evaluated again, just like the third part of a for loop in C.

Thus it can be used to increment a loop variable, even when the loop has been continued via the next statement. last, next, or redo may appear within a continue block.

Syntax

Following is the simple syntax for this function −

continue BLOCK

Return Value

This function does not return anything.

Example

Following is the example code showing its basic usage −

while (EXPR) {
   ### redo always comes here
   do_something;
} continue {
   ### next always comes here
   do_something_else;
   # then back the top to re-check EXPR
}
### last always comes here
