st: Re: Problem putting enclosed double quotes (was: Problem putting enclosed brackets).

[Amadou DIALLO <stata.diallo@gmail.com>]

Dear Nick,
Thanx for your answer. I have several purposes in doing that. But the
most urgent is that what I am currently doing is to pass a series of
matrices to Zurab's xml_tab (it is the code that suits most my needs
actually) and I want to preserve the labels of the modalities of my
hundreds of variables. For short labels, there is no problem. But for
long, spaced, labels, it's more complicated.

See the example below:

sysuse auto
tab  foreign rep78 , matcell(A)
loc vall : val la for
xml_tab A, rn("`: lab `vall' 0'" "`: lab `vall' 1'") // for my code rn
will be rn(`names')

Thx.
