[metapost] Problems to run mpost 1.206

[Carlos Ruiz Mora]

Hello,

I'm definitely new to MetaPost. I run the version that I got
with MikTex ver 2.7. I run it throug Crimson Editor. When I include
directives such as the one below (found in the MetaPost documentation
for version 1.206):
 ----------------------------------------------------------------------------------------------------

outputtemplate := "%j-%3c.mps";----------------------------------------------------------------------------------------------------

 
I get the following output message:
 
-------------------------------------------------------------------------------------------------

>> outputtemplate

>> "%j-%3c.mps"

! Equation cannot be performed (numeric=string).

<to be read again> 

                   ;

l.1 outputtemplate := "%j-%3c.mps";

                                   

I'm sorry, but I don't know how to make such things equal.

(See the two expressions just above the error message.)
------------------------------------------------------------------------------------------

So, it seems that the manual is wrong because lists the variable outputtemplate as string when it is recognized as numeric by mpost. So, I found out that I was running version 1.005. So I decided to find the latest version, which is 1.206. I now run that version 1.206 but now I get the following message:


---------------------------------------------------------------------------------------- 

---------- Capture Output ----------

> "C:\MetaPost\mpost.exe" Prueba2.mp

warning: kpathsea: configuration file texmf.cnf not found in these

Sorry, I can't find the 'mpost' mem file; will try 'plain'.

I can't find the 'plain' mem file!



> Terminated with exit code 1.
-------------------------------------------------------------------------------------------------------------------------- 

 So, I need help to understand what happens with the use of outputtemplate and how to make version 1.206 run normally. I get the same error even if I run it in console mode.

thanks a lot
Carlos.

PS: this is the test code I'm trying to run



outputtemplate := "%j-%3c.mps";
beginfig(1);
    fill fullcircle scaled 5cm withcolor red;
endfig;
beginfig(2);
    pair A, B, C;
    A:=(0,0); B:=(1cm,0); C:=(0,1cm);
    draw A--B--C--cycle;
endfig;
end

This is supposed to generate two files which names should be "fig-001.mps" and "fig-002.mps" according to the documentation for version 1.206
