Example:

In the following example, when enabling input %I0301 transitions off, register location %R0099 is loaded with the value 10, which is the function code for the Read Folder Name function. The Program Block READ_ID is then called to actually retrieve the folder name. The parameter block is located at address %R0100. READ_ID is also used in the next example.
