Forloop: too many variables specified r(103) error

[Hyunseo Yoo]

Hello,

I've been around for a year on this community, but this is my first post. I am running a forloop, and it gives me this error: too many variables specified r(103);.

Here is my code:

levelsof uscity if us == 1, local(uscitylist)
foreach city of local uscitylist {
    g `city'_NS = .
}

There are 9 items in local uscitylist. The code works for the first 5 items, and then gives the error.

How can I make the forloop work?


Thank you

Suppose the cities include Boston, Chicago and New York. Then Boston_NS and Chicago_NS work fine but

gen New York_NS = .

would trigger this error message. If you push your city names through strtoname() that should help.

. di strtoname("New York")
New_York

Thanks so much Nick Cox !! This code works nicely:

replace uscity = strtoname(uscity)

levelsof uscity if us == 1, local(uscitylist)

foreach city of local uscitylist {
    g `city'_NS = .
}
