It is the programmer’s lowest level of command interface tothe system instrumentation. You can use the library commands to configure the relay matrix andinstrumentation for parametric tests.This section lists the commands included in the LPT library and describes how to use them. Thedescriptions include:• A brief description of the command.• Usage, which shows how the command should be organized and descriptions of each parameter.The parameters that you need to supply are shown in italics. For example, for the commandint delay(long n);, replace n with the duration of the delay.• Detailed information about the command.• Examples that show a typical use of the command in a test sequence.The following conventions are used when explaining the commands:• All LPT library commands are case-sensitive and must be entered as lower case when writingprogram code.• Period strings (...) indicate additional arguments or commands that can be added.• Periods ( . ) indicate data not shown in an example because it is not necessary to help explainthe specific command.Section 13LPT library function reference
