The location of the variable
1-30
<min>
The lowest value of the interval
Integer
<max>
The highest value of the interval
Integer
<val>

Examples
ç
CALL /CTRL/VARS/V1:case(10 20 15)
æ
mO /CTRL/VARS/V1:case
A typical example when two different ranges of values have to meet:
Incoming values: between 0 and 255 (e.g. the slider of a controller can have these values).
Outgoing values: between 0 and 100 (e.g. the controlled device accepts these values).
Defined cases:
The command looks like:
ç
CALL /CTRL/VARS/V1:case(1 25 10;26 50 20;51 75 30;76 100 40;101 125 50;126 150 60;151 175 70;
176 200 80; 201 225 90; 226 255 100)
