Annemarie,

your example seems to be quite confused... a good advice might be to make sure that you truly understand the differences between variables and macros - the code you presented gives the impression that you confuse these concept a bit.

Implementing a counter in Stata, however, is pretty easy. Try something like

local i=0

foreach a of numlist 1/20 {

local i=`i'+1

di `i'

}

If you'd provide some more detail on what you're planning to do some more advice could potentially be given.

Cheers,

Christian

I am finding in Stata that there does not seem to be an easy way to increment a counter despite countless trys and readings of the manal.

I want to do something llike the following, this is just an example:

generate byte total_sum =0

for each variable of varlist {

if age > 50

total_sum = total_sum + age

}

Stata doesn't seem to allow the if... then construct unless it is in a program. Although I have written a simple program (crazy that I have to do this) passing arguments, I still can't get it to work.

I must be missing something.
