I found the following code, but it returns nothing. Why?

DECLARE INTEGER GetCurrencyFormat IN "kernel32" ;
INTEGER Locale,;
INTEGER dwFlags,;
STRING lpValue,;
INTEGER lpFormat,;
STRING lpCurrencyStr,;
INTEGER cchCurrency

cBuffer=SPACE(255)
cValue = "12345.6"
nLocale = 1033
GetCurrencyFormat(nLocale, 0, cValue, 0, cBuffer, Len(cBuffer))

* cBuffer is terminated with CHR(0)
cBuffer = LEFT(cBuffer,AT(CHR(0),cBuffer)-1)
