Description
If placed on the first line of a script, the script is opened into the debugger when it is run.

a first line that is blank followed by this comment negates the debug command.
Comparison Functions
The comparison operators (=) work for numbers, strings, and matrices. For matrices, they
produce a matrix of results. If you compare mixed arguments, such as strings with numbers or matrices, the
result is a missing value. Comparisons involving lists are not allowed and also return missing values.
The equality operators (== and !=) work for numbers, strings, matrices, and lists. For matrices, they
produce a matrix of results; for lists, they produce a single result. If you test equality of mixed results (for
example. strings with numbers or matrices) the result is 0 or unequal.
Range check operators let you check whether something falls between two specified values:
a=1;show(1
