functions in basfix.i - o

    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".
