for conditional handling question

[Keith Thompson]

so this could be the loop
e1; goto .2
.0: body;
.1: e3;
.2: if(e2) goto .0
.3:
if e2 is missing than e2=1
if body executes continue the for loop proceeds to .1: label
if the body has one break, proceeds to .3: label


and
while(e2)
{e3;
...
en;
}

is like

goto .1
.0: e3;
...
en;
.1: if(e2) goto .0
.2:
