I found this information in an old doc file, tS7_help.chm
Script commands can be run using following mask:
Library.RunCommand(<library name>, <category name>, <item name>)
For example:
Library.RunCommand('Commands','Script commands','Labyrinth')
When commands have parameters, use variants of the RunCommand method with parameters:
Library.RunCommand1<library name>, <category name>, <item name>, <param>)
Library.RunCommand2<library name>, <category name>, <item name>, <param1>,<param2>)
