Data Matrix Barcode help

I need a little assistance with the MakeDataMatrixBarcode Function. Here is the code I currently have

var ID = Field("Partner ID")
var Appeal = Field("Appeal")
var Segment = Field("AppealSegment")
return MakeDataMatrixBarcode (ID+"  "+Appeal+"  "+Segment+"  ", true, "ASCII", 4, 7)

Specifically I need to know how to input a tab into the fields. It needs to be a horizontal tab of ASCII value 09. If I manually place a tab " ", the rule editor converts it to double-spaces.

Any assistance would be greatly appreciated.

Edit: I read the System Guide for this function, and used the requested "~009", but the string (ID+~009+Appeal+~009+Segment+~009, true, "ASCII", 4, 7) doesn't come through correctly.

The way to encode a tab character in JavaScript is either "\t" or String.fromCharCode(9). You can also use FusionPro's Chr helper function, e.g. Chr(9).

You can use the tilde escapes (since you have the second parameter of the function set to true to enable them), but you still need to specify them as strings to the function by quoting them:

return MakeDataMatrixBarcode(ID+"~009"+Appeal+"~009"+Segment+"~009", true, "ASCII", 4, 7)
