USERDATA Property

The USERDATA property allows application data to be assigned with individual objects. This gives a PLB user applications a way to assign specialized data to an object to be used as needed. The property uses the following format:

USERDATA={value}

Note the following:

1. USERDATA may be used in CREATE, SETPROP, or GETPROP statements of all objects.

2. {value} is a character string variable or literal.

3. The maximum length for a USERDATA string is 40960 bytes.

4. The USERDATA string is expected to have ASCII data with character values larger than 0x20. A binary value of zero is not prevented but can cause the userdata string to be truncated using a GETPROP.
