MPost: how to pass variables from mpost to TeX.

MPost: how to pass variables from mpost to TeX.

[vinuth madinur]

Hi everyone,
              My mpost doesn’t have “textext” macro.
So, what are the other ways of doing it? 

What I want to do is this :
 
%I have a variable “GbLableName”
GbLableName=”B_2”;

%Now I want to use this variable like this:

lable.bot( btex GbLableName etex , (0,0) );

But this will just display “GbLableName” instead of “B_2”.

So can someone please tell how this can be done? I know too little about TeX.

Someone suggested about using  “Textext” macro. But my MPost version doesn’t have it. 
So are there any other ways of doing it?

Looking forward for it……..

Vinuth.M.Madinur.

Sorry, I thought you were using metafun (since you asked on the
ConTeXt mailing list I didn't think of using plain mp)

You have to do something like that is described at:

(I hope I understand your problem right)

btex ... etex is scanned by some mp tools and then tex'd; no expansion takes place then, so GBLableName becomes text

textext is more clever; 

why not use metafun then? it has everything metapost + more 

also, 

\starttext 

\startMPpage 
   your code 
\stopMPpage 

\stoptext  

with 

(texexec --pdf thatfile.tex) 

will work ok; from within metafun/context you can use text variables (\MPstring and such); see metafun manual
