The output you get from this example may vary depending on the data format settings of the
instrument.
Example: Loop array
i = 1
while atable[i] do
print(atable[i])
i = i + 1
end
Defines a table with four numeric elements.
Loops through the array and prints each
element.
The Boolean value of atable[index]
evaluates to true if there is an element at that
index. If there is no element at that index, nil is
returned (nil is considered to be false).
Output:
1
2
3
Standard libraries
In addition to the standard programming constructs described in this document, Lua includes
standard libraries that contain useful functions for string manipulation, mathematics, and related
functions. Test Script Processor (TSP
®
) scripting engine instruments also include instrument control
extension libraries, which provide programming interfaces to the instrumentation that can be
accessed by the TSP scripting engine. These libraries are automatically loaded when the TSP
scripting engine starts and do not need to be managed by the programmer.
The following topics provide information on some of the basic Lua standard libraries. For additional
information, see the Lua website (lua.org
).
When referring to the Lua website, please be aware that the TSP scripting engine uses Lua 5.0.2.
