ADDITION FOR PACKED DECIMALS:
Packed decimal fields are usable as they are with no conversion. But if you 
have negative numbers in unpacked fields, they contain a character as the last 
digit that will need to be changed to the correct number and then
multiplied by -1 to get the right number. I am attaching a function that
will change the character to a number and return True if the number needs to
be multiplied by -1 for the correct result.

A example of it's use is,

IF IbmNumToPc(IbmNum) THEN
  NewVariable = IbmNum  *  -1
ELSE
  NewVariable = IbmNum
END


IbmNumToPc          Function(IbmNum)

Loc:String      cstring(20)
loc:Length      short

  code

  loc:String = IbmNum
  loc:Length = len(loc:string)

  if numeric(loc:string[loc:length]) then
    return(False)
  else
    case loc:string[loc:length]
      of '}'
        IbmNum[loc:length] = '0'
      of 'J'
        IbmNum[loc:length] = '1'
      of 'K'
        IbmNum[loc:length] = '2'
      of 'L'
        IbmNum[loc:length] = '3'
      of 'M'
        IbmNum[loc:length] = '4'
      of 'N'
        IbmNum[loc:length] = '5'
      of 'O'
        IbmNum[loc:length] = '6'
      of 'P'
        IbmNum[loc:length] = '7'
      of 'Q'
        IbmNum[loc:length] = '8'
      of 'R'
        IbmNum[loc:length] = '9'
    end
    RETURN(True)
  end
