nop operation?
I was curious how CAS handles parsing when spaces are put in composite operators.
I typed: typed LHS of stack RHS of stack a:=3 3 a+=1 increment(a) 4 a+ =1 a+nop(1) 5 What is the nop operation? I tried the help command and it isn't documented. Thanks Donald

RE: nop operation?
nop does nothing (means no operation)

RE: nop operation?
So, nop(1) means 1?

RE: nop operation?
More precisely, nop(1) evaluates to 1.

RE: nop operation?
Xcas
[subst((abs(2*x1)) = 1,'abs','nop'), subst((abs(2*x1)) = 1,'abs','neg')] returns [(2*x1) = 1, (2*x+1) = 1] http://www.hpmuseum.org/forum/thread857...hlight=nop
