st: RE: grqreg for Stata 7

[Puja Vasudeva <p.vasudeva@sussex.ac.uk>]

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....
