Hi!
Why you use 'Allt(str(asc(' for fread??? fread already returns data you need. They will be binary data in the VFP character string. VFP character strin can contain eny codes include zero code (Zero byte don't cause VFP string to finish). So feel free to use VFP character strings to store any binary data - be sure data will not be corrupted.
Following is my edition of your sample:
bytes = fread(f_hand,2)
Number = ascc(left(pcValue,1)) + ;
asc(substr(pcValue,2,1))*256
You need nothing else!
HTH.

The professional level of programmer could be determined by level of stupidity of his/her bugs
It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
