Greetings,

Am I missing something obvious, or is there something weird about how
Stata chokes on the following program -mytest-, but does not choke on
-mytest2-?  That is, using a macro to selectively comment out lines of
code seems to work, except when it is within an -if- block :

program define mytest
   if `1'==1 {
	`2' if `3'==1 {
	`2'	di "three is set to one"
	`2' }
   }
   else {
	`2' if `3'==1 {
	`2'	di "three is set to one"
	`2' }
   }
end

prog define mytest2

	`2' if `3'==1 {
	`2'	di "three is set to one"
	`2' }

end

. mytest 1 " " 1
three is set to one
unrecognized command:  } invalid command name
r(199);

. mytest 1 "*" 1
unrecognized command:  } invalid command name
r(199);

. mytest2 1 " " 1
three is set to one

. mytest2 1 "*" 1
