The I Edit Descriptor
The value of n is 4 for Gw.d format and (e+2) for Gw.dEe format. The n(‘ ’) used in the
above example indicates
nth number of blanks. If the F form is chosen, then the scale
factor is ignored. The following comparison between F formatting and G formatting is
given by way of illustration:
When an overflow condition occurs in a numeric field, the field is filled with asterisks (in
the absence of any specification to the contrary by an overflow decoration), as shown
above.
The “|” character is used to denote the boundaries of the output field.
The I Edit Descriptor
The integer edit descriptor is used to display or interpret data values in an integer form.
The I edit descriptor has the following forms:
I
w OR Iw.m OR Iw.m.b
w an unsigned integer constant that defines the total field width and cannot
exceed 255. The field processed is the
w characters starting at the current
position. After the field is processed, the current position is advanced by
w
characters.
m an unsigned integer constant that defines the number of digits that must be
present on output.
10 ** (d-2) 10 ** (d-1) F(w-n).1,n(' ')
10 ** (d-1) 10 ** d F(w-n).0,n(' ')
10 ** d Ew.d or Ew.dEe
