9.6.1 Variables
A variable is a packet of memory, given an alphanumeric name, through which
pass measurements and processing results during program execution. Variables
are declared either as Public or Dim at the discretion of the programmer. Public
variables can be viewed through software numeric monitors. Dim variables
cannot. Up to 128 public variables can be declared in a CR200(X) program and
up to 48 public variables declared in a CR200 program.
