st: If-command not accurate

["Daniel Brodback" <schmani@gmx.de>]

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 PF_lret6?

Kind regards,

Daniel
