Is there a pre-existing function to convert a integer/byte (0-255) into an string containing a single ASCII character? BYTE_TO_STRING is close, but I want the value 65 to return "A", not "65".
Seems like maybe there could be, but I can't find it. I'm looking to display ASCII values stored as INTs in a ScadaPack and read as Modbus into a string variable in Geo SCADA Expert (CS2017

I suspect unfortunately you might have to write you own Logic Library for this.
Geo SCADA Expert doesn't have the concept of a 'CHAR' data type, it's just a single element STRING.
So if you create a ST Library, and then have a CHAR or CHR function defined within it that took an INT (or BYTE) and returned a single element STRING, then you'd be able to do what you're looking for.
You'd just want your function to have a big CASE block... one condition for every character you want to map.
Or I guess you could do it with an array and then a lookup into the array, this might actually be nicer,
or even a STRING with all the characters, and then use MID to pull out the right value.
