=: (%, %) -> Boolean
from BasicType
~=: (%, %) -> Boolean
from BasicType
close!: % -> %
close!(f) returns the file f closed to input and output.
coerce: % -> OutputForm
from CoercibleTo OutputForm
flush: % -> Void
flush(f) make sure that buffered data in written out to the operating system.
hash: % -> SingleInteger
from SetCategory
hashUpdate!: (HashState, %) -> HashState
from SetCategory
iomode: % -> String
iomode(f) returns the status of the file f. The input/output status of f may be “input”, “output” or “closed” mode.
latex: % -> String
from SetCategory
name: % -> Name
name(f) returns the external name of the file f.
open: (Name, String) -> %
open(s, mode) returns a file s open for operation in the indicated mode: “input” or “output”.
open: Name -> %
open(s) returns the file s open for input.
read!: % -> S
read!(f) extracts a value from file f. The state of f is modified so a subsequent call to read! will return the next element.
reopen!: (%, String) -> %
reopen!(f, mode) returns a file f reopened for operation in the indicated mode: “input” or “output”. reopen!(f,"input") will reopen the file f for input.
