Hi Jim:
That part worked thanks! However, if have not gotten
the results that I had hoped for.
I had assumed that skip fp 10 would take me to offset
10. It appears that it has not.
TestBin.txt contains the characters:
"abcdefghijklmnopqrstuvwxyz"
The following code :
;===============================================================
fp: open/read/direct/binary %TestBin.txt
skip fp 10
print to-string buffer: copy/part fp 10
close fp
;===============================================================
produces:
>> do %BinFile.r
abcdefghij
The result I would be looking for in buffer
would be "klmnopqrst"
So it appears that skip fp 10 is not advancing
the "file pointer" to offset 10.
what would I do to make that happen?
Thanks
Tim
