Here is a code that generates a compiler error:
"Unable to find Visual class library ERROR"
NEWOBJECT('frmMessageBox', 'base.vcx', '', ThisForm, ;
'This barcode is not recognized as a User ID. ' + CHR(13) + ;
'Click OK if you want to scan the ID again', 'Error', 2)

If I remove CHR(13) then it compiles without the error. What am I missing?

Thanks
