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 [b]$[/b]”String”[b]$[/b]. E g.:
[code]
$”DataSignal1″$ // equal to DataSignal1
[/code]
[b]Note[/b] 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:
[code]
$”sin”$(1) // equal to sin(1)
[/code]
Note that instead of literally specifying the string it is of course possible to use a variable which contains the string.
