stupid question but please help, saving record data

I need to save a series or data of a record type (let's say a.name
a.tel)
but when i retrieve what i saved the program tells me "read beyon end of

file", now, this is simple pascal here, no rocket science, i create the
file with rewrite, then write the first (or several) record, then close
the file, when i need to add i open it with appends and read from it
with read, what's wrong then?

any ideas?

thanks! please e-mail the answer too

Re:stupid question but please help, saving record data


Try opening the file with reset if you want to read. Open it with append,
sets the file pointer at the end of the file so you can append more data to
it.

If you're opening with append... you may want to seek to the record number
you wish to read ;)

given that 'n' is the record number... and 'F' is the filehandle...

seek(F,n-1);
read(F,recordname);
