Here's the two ways I end up using to do this. The quick and easy way:

layr = strtrim(lay + 1, 2)

STRTRIM will convert a number type to a string and also remove
whitespace, here the "2" indicates to remove leading and trailing
whitespace.

Or I might do something like this:

filename = string(outdir, sim, lay + 1, pol, $
format='(%"%s/emissions_%s_air_level%d_%s.ps")')

You can also use Fortran style format codes, I am just more familiar
with the C ones.
