|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
00010A          R RECORD
00020A            F1             5Y 0B  3  4VALNUM
00030A            F2             5Y 0B  4  4

In this example, field F1 will not allow the user to embed a SPACE, the PLUS SIGN or MINUS SIGN within the numeric value or precede the numeric value with a PLUS SIGN or MINUS SIGN. Field F2 will be treated as described in "DDS Data Type/Keyboard Shift (Position 35)".
