This option sets the character used for the decimal point for singles and fusing.
CONFIG DP= "dp"
The decimal point is a dot (.) by default. The STR() and FUSING functions convert a single into a string. The fraction is separated by a dot. In a number of counties the comma is used as a separator.
Valid options are : CONFIG DP = "." and CONFIG DP = ","
New preferred Syntax:
Valid options are : CONFIG DP = DOT and CONFIG DP = COMMA

CONFIG DP = ","
Dim s as single
S = 1234.56
