Recently I was looking at an algorithm in one of Knuth's books.
The algorithm is described in steps with many of the form
if condition 1 then goto step 7; if condition 2 go to step 8,
etc.
I managed to write up the algorithm by making each step
a procedure, but had trouble with handling global variables.
Is there in Maple some standard method for dealing with such algorithms.
A friend tells me that in some languages there are "cases" and
"switches" that can be used. Is there any thing like that in Maple?
Thanks,
Edwin
