If the file is not too big, you can use something like this:

lcFile=yourfile
lcTekst=filetostr(lcFile)
lnLength=len(lcTekst)
strtofile(lcFile,left(lcTekst,lnLength-30))

NB! Not tested. And be sure to make a backup first. :-)

>I have this corrupted table. the records and it's length seems to be okay, but the header has somehow got 30 characters more in it, though this longer header is still recognized by FP and still returns the right number of fields, fieldnames and lengths.
