macros and buffers

macros and buffers

[Matthew Huggett]

Hi:

Recently, I had some data I wanted set using tabulate but in 7 individual
buffers.  I wanted to use a macro to both create the buffers and do the
\starttabulate...\stoptabulate stuff.  I found that my macro could create
the .tmp file for each buffer but that the files were all empty.  Why would
this happen, and is there a way to make this work?

example:

\define[5]\MyBuffers{
  \startbuffer[#1]
    \starttabulate[|l|l|]
      \NC #2 \NC #3 \NR
      \NC #4 \NC #5
    \stoptabulate
  \stopbuffer
}

Best Wishes,

Matthew Huggett

this is because buffers do a copy based on grabbing lines; in your case, 
use \setbuffer[#1]...\endbuffer

(you're lucky, the next release will provide \usememorybuffers, since a few 
days back we needed something similar)
