String as a signal name in a FPScript formula

There is a string in a FlexPro formula. How to call a signal that has the same name as the value of a string?

Do do that, you need to use the FPScript “Indirection” operator $“String”$. E g.:

$"\Data\Signal1"$             // equal to DataSignal1

Note that the backslash characters have to be doubled because the backslash is the escape character in FPScript strings!

You can use the indirection op to call functions also:

$"sin"$(1)          // equal to sin(1)

Note that instead of literally specifying the string it is of course possible to use a variable which contains the string.
