It's fairly simple to do; FSEEK() returns the offset from the beginning of the file after it fires, so the following code fragment shows how to do an FGETS() and go back to where the file pointer was when you started:
* nFH is the file handle returned by FOPEN()
LOCAL lnFilePos, lcInputBuffer
lnFilePos = FSEEK(nFH,0,1) && go 0 bytes from where you are
lcInputBuffer = FGETS(nFH,
max # of bytes to accept without a CR)
=FSEEK(nFH,lnFilePos,0)
