Thanks very much for this tip, Nick. It worked fine, provided the locals were defined first:
local x1: word count `rhs'
local x2: word count `varlist'
if `x1' <= `x2' {
local graphvars "`rhs'"
}

.. and then I run into problems with the graph command. This is the Stata 8 version:

graph twoway `cicmd' `olscmd' `olscicmd' (scatter `name' qtile,c(l)
legend(off) msize(tiny) clwidth(medthick) title(`tname') ytitle(`varlab') xtitle(Quantile) nodraw name(`graphname', replace))

Stata 7 doesn't support this syntax but I can't seem to figure out how to translate this. Any ideas would be much appreciated.
Sorry, I know this is asking a bit much and I should upgrade like the
rest of the world....

The code

if wordcount("`rhs'")<=wordcount("`varlist'") {
local graphvars "`rhs'"
}

can be translated

if `: word count `rhs'' <= `: word count `varlist'' {
local graphvars "`rhs'"
}

This should work in Stata 7 too. It may not be
documented for 7. Make sure you use the correct single
quotes.

Of course, you should upgrade to Stata 8 too....

I found mention of grqreg.ado in the Statalist archives for
graphing the
coefficients of a quantile regression
(<http://www.stata.com/statalist/archive/2004-01/msg00552.html>).

My problem is that I use Stata 7 and this ado file was
written for Stata 8.
I can change most of the syntax to make it run in Stata 7 -
except the
function "wordcount".  Does anyone have a modified version to
run on Stata
7? Failing that, can anyone tell me the Stata 7 equivalent of
wordcount?
