PIC supporting plus and minus symbols

Try PIC 9(2)  or PIC 9(2)

There are additional options depending on whether you want the symbol fixed on the left, floating right to just before the first significant digit, blank when zero.  Also you can have two digits with a leading 0 or, in the case of values 0 - 9, a single digit with a leading space.

     *> BWZ == BLANK WHEN ZERO

     *> fixed == plus sign in fixed position

     *> floating == plus sign floats to right

      01 num01  pic (3).   *> floating ; implicitly BWZ

      01 num02  pic (3) blank when zero.  *> floating ; explicitly BWZ

      01 num03  pic z9.   *> fixed ; one digit for 0 - 9

      01 num04  pic 9.   *> floating with one digit for 0 - 9

      01 num05  pic 99.   *> fixed   with two digits for 0 - 9

      01 num06  pic zz.   *> fixed   ; implicitly BWZ
