# st: A couple of file command questions for writing a .tex program

Fellow listers,

I am trying to learn to write Latex files from Stata/Mata with the
file commands and have a couple of questions:

1.  What is the difference between using simple quotes " xxx "
compared with " xxx "' type quotes?  The user manual displays simple
quotes for write commands

file write handle "first part is"

while in the Gini/Pasquini' Automatic Generation of Document article
from Stata Journal vol 6 number 1, the typical example
uses a format like,

file write handle  "first part is"'

I would like to know how they are treated differently, if at all.

2.  A more complicated question.  How does one use a $sign in a file write command and not have Stata treat it as a global macro? For instance, the end of the following command: file write tex "\begin{tabular}{lrrrrrrrrrrr}\hline\\ \scriptsize Model & : word 1 of :colname e(b)'' & p-val & " file write tex ": word 2 of :colname e(b)'' & p-val & : word 3 of :colname e(b)'' & p-val & : word 4 of :colname e(b)'' & " file write tex "p-val & : word 5 of :colname e(b)'' & p-val & adj.$R^2$\\" _n file write tex "\vspace{0.05in}" _n generates: \begin{tabular}{lrrrrrrrrrrr}\hline\\ \scriptsize Model & FFMkt & p-val & SMB & p-val & HML & p-val & UMD & p-val & _cons & p-val & adj. ^2$ \\

and I end up with ^2$as opposed to the$R^2$term I need for a Latex math string. I also tried =char(35)'R^2$

without any change in results.  Any suggestions would be much appreciated.

Thanks,

Tom
