Title
[P] continue -- Break out of loops
Syntax
continue [, break]
Description
The continue command within a foreach, forvalues, or while loop breaks
execution of the current loop iteration and skips the remaining commands
within the loop. Execution resumes at the top of the loop unless the
break option is specified, in which case, execution resumes with the
command following the looping command. See [P] foreach, [P] forvalues,
and [P] while for a discussion of the looping commands.
Option
break indicates that the loop is to be exited. The default is to skip
the remaining steps of the current iteration and to resume loop
execution again at the top of the loop.
Examples
forvalues x = 1/10 {
if mod(`x',2) {
display "`x' is odd"
continue
}
display "`x' is even"
}
would produce the same results as
forvalues x = 1/10 {
if mod(`x',2) {
display "`x' is odd"
}
else {
display "`x' is even"
}
}
The break option allows you to prematurely exit the loop.
forvalues x = 6/1000 {
if mod(`x',2)==0 & mod(`x',3)==0 & mod(`x',5)==0 {
di "The least common multiple of 2, 3, and 5 is `x'"
continue, break
}
}
The loop is executed over the values of 6 to 30 instead of to 1000.
