(unknown charset) reports25 question

my rdf uses a (data mode --> user parameters) P_1

(dataype is character and length is 9, data/selection is a select statement,no conflict with P_1)

which is source of  (parameter form -->fields) PF_1

How to do a format mask to PF_1 like 999"/"99"/"99  (that is 1111111 --> 111/11/11)

appeared in the runtiime parameter form ?

Thanks You !
