The FLDSTRT system initialization parameter specifies a single character to be the field-name-start character for free-form input for built-in functions.
The character specified in the FLDSTRT parameter must not be the same as any character specified in the FLDSEP parameter. This means that it is invalid to allow both parameters to take the default value.
Restrictions If you specify FLDSTRT in the SIT, the parameter must be enclosed in single quotation marks.
