C Example 1

     BOOL fOK;
int  iSession;

fOK = LceSetFieldValueU(iSession, "TOWN", "宮代町");

C Example 2

     BOOL fOK;
int  iSession;

fOK = LceSetFieldValueU(iSession, "TOWN", NULL);

C Example 3

     strcpy(strField, "TOWN");
if !LceSetFieldValueU(iSession, strField, "Henty")
{
         /* return error */
}
Note: You are not assigning strField = "12345". You are assigning the field "EMPNO", which happens to be stored in the variable strField, to the value of "12345".
