RE: Packed data

>If the final hex digit is not F, the number is negative.

Not necessarily. If it's not F it's usually D which is indeed negative.
Generally you are unlikely to encounter sign digits other than these unless
the file originated on another system. However, hex digits A, C, E and F are
all treated as positive signs. Only B and D are negative.

     Robert,
     
     When you DSPPFM, use F10 to display the data in hexadecimal format.  
     This will allow you to decipher the packed fields.  For example, the 
     value 12 stored in a 3-byte packed field will display as 00012F.  If 
     the final hex digit is not F, the number is negative.
