Postfile does not work after user written command

[Pablo Bonilla]

Hi all,

For some reason Stata does not find my postfile after a user written command is executed. The really weird thing is that the first time I execute my do-file (let’s call it do-file A) the code does NOT run and an error message saying, “post postname not found” appears. However, if I execute do-file A again immediately after the first time, the code DOES run. So far, not big deal. The problem however arises when do-file A is called or used by another do-file (let’s call it do-file B). No matter how many times I execute do-file B, it will never run and I always get the same error.
Do-file A is something like this:

drop _all
postfile f str15(country year text) using file, replace
local countries "pry hnd"
local years "2005 2007"
 
foreach country of local countries {
            foreach year of local years {
                        user_command [syntax]
                        post f ("`country'") ("`year'") ("this is a test")
            }
}
 
postclose f
use file, clear
exit

I already checked the user written command (user_command.ado) and it does not have any "clear" or “clear all”, it only has “drop _all” and “preserve.” Also, neither do-file A or B has any “clear” or “clear all.”

Any help would be highly appreciated.
Thank you in advance,

Pablo
