Macros are collections (subroutines) of global commands. An example is:
< run
probname
solve
show V100
contour
>
This macro assembles the problem whose name is probname, solves
the large sparse matrix system that results, prints out information
about the solution and displays its contour plot. It is invoked by
typing the name run.
Macros are delimited by < and >. Fasttalk commands can be abbreviated to their first four letters, and their precise meaning can always be found through the alphabetical index of the on-line Reference Manual.
