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
>>> Stata expects there to be something within an -else-.
In principle, it is not an error to ask Stata to
do nothing. In practice, an -else- branch with nothing
in it is, I guess, usually a programmer error.
