{bf:[M-2] continue -- Continue with next iteration of for, while, or do loop}


{title:Syntax}

{title:Description}

{p 4 4 2}
{cmd:continue} restarts the innermost {cmd:for}, {cmd:while}, or {cmd:do}
loop.  Execution continues just as if the loop had reached its logical end.

{p 4 4 2}
{cmd:continue} nearly always occurs following an {cmd:if}.


{title:Remarks}

{p 4 4 2}
The following two code fragments are equivalent:

	{cmd}for (i=1; i<=rows(A); i++) {
		for (j=1; j<=cols(A); j++) {
			if (i==j) continue
			{txt}... action to be performed on A[i,j] ...{cmd}
		}
	}{txt}

{p 4 4 2}
and

	{cmd}for (i=1; i<=rows(A); i++) {
		for (j=1; j<=cols(A); j++) {
			if (i!=j) {
				{txt}... action to be performed on A[i,j] ...{cmd}
			}
		}
	}{txt}

{p 4 4 2}
Note that {cmd:continue} operates on the innermost {cmd:for} or {cmd:while} 
loop and that, even when the {cmd:continue} action is taken, standard 
end-of-loop processing takes place (which is {cmd:j++} is this case).
