Easy:
2,123,456,789 in hex is: 7E, 91, 61, 15
Convert these bytes back to decimal:
126, 145, 97, 21
So to store this number in 8 characters you would use:
Chr(0) + Chr(0) + Chr(0) + Chr(0) + Chr(126) + Chr(145) + Chr(97) + Chr(21)
(this assumes big-endian 'most significant byte first' format...)
Which should work, but I don't know if fox will mess up the character codes...
BINTOC(2123456789,"S") almost does what you want but only returns 4
bytes (unless it's a float)
n = 2123456789
a=BINTOC(n,"S")
FOR x=1 TO LEN(a)
??ASC(SUBSTR(a,x,1))
ENDFOR
= 126, 145, 97, 21
You probably don't want to work with big-endian format if you're
talking to other systems as Intel chips use little-endian.
Let me know if you need any help!
