Thanks for the replies folks. The example that I posted is a simple example. The example that I'm working on (displaying successive terms in a Taylor series) requires a bit of computations, and I don't want to have to go back and do each computation for each value of #1. That is, I want to build a table of numerical values (numeric Y[][]) and be able to address those values from my \startMPcode section. If I have two different \startMPcode ... \stopMPcode sections, is there a way (perhaps it does this by default) to have the variables stored in the first block available in the second block? In pure MetaPost, I can do numeric a:=4; beginfig(1); label(decimal(a),origin); endfig; beginfig(2); label(decimal(a),origin); endfig; end and both figures have the value of 'a' available to them because 'a' was defined before each figure. What is the ConTeXt way of doing this? Thanks, Troy
