Test Script Language (TSL) reference
Introduction
A script is a program that the Test Script Processor (TSP) executes. A script is
written using the Test Script Language (TSL). TSL is an efficient language, with
simple syntax and extensible semantics. TSL is derived from the Lua
programming language, Copyright

Variables and types
TSL has six basic types; nil, boolean, number, string, function, and table. TSL is a
dynamically typed language, which means variables do not need to be declared
as a specific type. Instead, variables assume a type when a value is assigned to
them. Therefore, each value carries its own type. If a variable has not been
assigned a value, the variable defaults to the type nil. All numbers are real
numbers. There is no distinction between integers and floating-point numbers in
TSL.
var = nil
-- var is nil.
var = 1.0
-- var is now a number
.
var = 0.3E-12
-- var is still a number.
var = 7
-- var is still a number.
var =
"
Hello world!
"
-- var is now a string.
var =
"
I said, Hello world!
"
-- var is still a string.
var = function(a, b) return(a+b) end
-- var is now a function
that adds two numbers.
var = {1, 2., 3.00e0}
-- var is now a table (i.e.,
array) with three
initialized members.
