st: r(198) error with a foreach loop - problem with '`'

[Jamie Fagg <j.fagg@qmul.ac.uk>]

Dear Statalist,

Firstly, thanks to Nick Cox and Austin Nichols for their reply to my
recent question about -esttab-. Both answers provide helpful clues to
where I should be going with the problem, but both also raised some
extra questions which I haven't had a chance to work through yet.

On a separate note, Stata is suddenly telling me that ` is not valid
in my foreach loops and I cannot work out where to look to identify
the problem. Code illustrating the issue is below.

Thanks

Jamie

//show that file exists
. use Work\Datasets\Source\dyouth,clear

. des, short

Contains data from Work\Datasets\Source\dyouth.dta

size:        98,171 (99.9% of memory free)
Sorted by:

//show error with foreach loop
. foreach w in d {
 2.         use Work\Datasets\Source\`w'youth,clear
 3. }
invalid '`'
r(198);

end of do-file

r(198);


Thanks

Jamie
