The persistent System Register are used to store profile global variables.

One usage is to store the product name when changing toolbox - see Toolbox Switch example.

There is a total of 48 registers available of three types:

• Text registers - T0,T1,,,,T15
• Scalar registers - S0,S1,,,S15
• Logic / boolean registers - B0,B1,,,B15

The text register is available from the tag browser.

Note: The system register is always available and does not require a tool declaration to be available - like the Data tools.

Example 1: Read Text Register T2

text = GetStringValue('Register.T2')

Example 2: Set Boolean Register B1

SetBoolValue('Register.B1',1)
