Re: Using files as externally described as program decsribed

["Jim Franz" <jfranz@xxxxxxxxxxxx>]

system has no problem opening a file where F specs record length
is more than real file. just never use a described field in the program
past the real record length. Also be aware that at run time, an ovrdbf
can override to any file on disk.
There is no requirement for internal field specs to match external file
definition, or to internally describe all fields.
You can have serious errors if add records do not update
all the numeric fields.
