Hi

x=NULL
? STR(null)

OK : STR return NULL
BUG : NULL type is not "C"; LTRIM(),RTRIM()... return NULL "C" type correclty

? STR(x)

BUG: STR return error type

For VFP Team: solution

your internal code is:
if (parameterType#'C')
Error;
if (parameterValue=NULL)
return parameterValue;

correct is ( LTRIM .. RTRIM uses this schema ):
if (parameterValue=NULL)
return charsNullvalue;
if (parameterType#'C')
Error;
