st: QUestion using -fs- package

["Nuno Soares" <ndsoares@gmail.com>]

Hi everyone,

I'm using the -fs- command to look into a directory for several files, open
them, insert a new variable with the file name, and save them. The code is
the following:

qui fs *.dta
foreach f in `r(files)' {
	use `f', clear
	cap drop file
	gen file=`f'		
	save, replace
}

However, when I run the code I get the following error code:
wscopear:  operator invalid
r(198);

Basically the gen file=`f' command is returning the above error. Any way of
doing what it is intended to do?

All the best,

Nuno
