Your title is misleading. You need

if "'var'" == "PF_ret6" {

(there doesn't seem to be a single left quotation mark on the device I am using). You are looking for a match on names, not values.

Dear all,

in a foreach-loop, I am trying to "catch" a specific case and therefore I implement this with an if-command.

For my varlist, I want certain commands to be executed but when var "PF_ret6" occurs, I need different commands.

I implemented this in the following way (Stata SE 11.2):

foreach var of varlist PF_dy-PF_ret6 {
   if `var' == PF_ret6 {
...
}
else
{
}
}

The weird behavior is, that for the first variables everything works as expected. But when the variable prior to PF_ret6 is reached (named PF_lret6), it also enters the if-condition.
Is there a way to assure that the if-command only uses PF_ret6 but not
