obasis

file= obasis(filename)

or file= openb(filename)

or file= openb(filename, clogfile)

(If you typed help,openb and are reading this, then consider the

latter two forms. If you typed help,obasis, consider the first.

In either case, the original openb function is called basfix_openb.)

open the existing file FILENAME for read-only binary I/O.

(Use updateb or createb, respectively, to open an existing file

with read-write access or to create a new file.)

If the CLOGFILE argument is supplied, it represents the structure

of FILENAME in the Clog binary data description language.

After an openb, the file variable may be used to extract variables

from the file as if it were a structure instance. That is, the

expression "file.var" refers to the variable "var" in file "file".

A complete list of the variable names present in the file may

be obtained using the get_vars function. If the file contains

history records, the jt and jc functions may be used to set the

current record -- initially, the first record is current.

The restore function may be used to make memory copies of data

in the file; this will be faster than a large number of

references to "file.var".

open

f= open(filename)

or f= open(filename, filemode)

or f= open(filename, filemode, errmode)

opens the file FILENAME according to FILEMODE (both are strings).

If ERRMODE is non-nil and non-zero, fail by returning nil F,

otherwise failure to open or create the file is a runtime error.

To use ERRMODE to check for the existence of a file:
