The Add-On works the same way the GDL file operations. You have to open a channel, read the information and close the channel.
This Add-On is also available by using the REQUEST GDL command, in which case the sequence of commands OPEN, INPUT and CLOSE is called internally.
This is the simplest way to obtain the date/time information, with just a single GDL command line:
REQUEST ("DateTime", format_string, datetimestring)
The second parameter of the Request function is the same as that described in the OPEN function paramstring parameter.
Its return value is a positive integer that will identify the opened channel. This value will become the channel’s future reference number.
The paramstring can contain specifiers and other characters.
