GN_Pdn, Write binary integer number as decimal ASCII string

Register parameters

RST 20H, DEFW $1209
IN:
     HL = 0, not allowed
     HL = 1, not allowed
     HL = 2, convert 16bit integer in BC
     HL > 255, HL points at 32bit integer to convert

     DE = 0, write result to stream IX
     DE = 1, write result to filter IX
     DE > 255, result is written at (DE)

     A = formatting specifier
          A0 = 1, disable leading zero blanking (ie. no leading spaces)
          A1 = 1, output leading space
          A2 = 1, output trailing space
          A4->A7, numeric field width (0 = as large as is required)

     IX = optional result handle (if DE = 0,1)

OUT, if call successful:
     Fc = 0
     DE points to character after result (if DE(in) > 255)

OUT, if call failed:
     Fc = 1
     A = error code
Registers changed after return:
     ..BC..HL/IXIY same
     AF..DE../.... different 

Notes

Leading/trailing spaces only effective if numeric field width is given.
