output to the pager as soon as it is available.

Print a title string followed by a series of options.
Read a single keystroke from the keyboard.
Save the named variables V1, V2, .
Load the named variables V1, V2, .
Query or set the internal variable that specifies the default options
for the `save' command, and defines the default format.
Query or set the internal variable that specifies the number of digits
to keep when saving data in text format.

Read the matrix DATA from a text file.
Write the matrix X to a file.
Read the matrix X from a file.
Query or set the internal variable that controls whether Octave tries
to save all current variables to the file "octave-core" if it crashes
or receives a hangup, terminate or similar signal.
Query or set the internal variable that controls whether Octave tries
to save all current variables to the file "octave-core" if it receives
a hangup signal.
Query or set the internal variable that controls whether Octave tries
to save all current variables to the file "octave-core" if it receives
a terminate signal.
Query or set the internal variable that specifies the options used for
saving the workspace data if Octave aborts.
Query or set the internal variable that specifies the maximum amount of
memory (in kilobytes) of the top-level workspace that Octave will
attempt to save when writing data to the crash dump file (the
Query or set the internal variable that specifies the name of the file
used for saving data from the top-level workspace if Octave aborts.
Find a rational approximation to X within tolerance defined by TOL
using a continued fraction expansion.
Convert X into a rational approximation represented as a string.
Return the numeric value corresponding to the standard input stream.
Return the numeric value corresponding to the standard output stream.
Return the numeric value corresponding to the standard error stream.
The first form of the `fopen' function opens the named file with the
specified mode (read-write, read-only, etc.
Closes the specified file.
Write a string to a file with no formatting.
Write a string to the standard output with no formatting.
Read characters from a file, stopping after a newline, or EOF, or LEN
characters have been read.
Read characters from a file, stopping after a newline, or EOF, or LEN
characters have been read.
Print optional arguments under the control of the template string
TEMPLATE to the stream `stdout' and return the number of characters
printed.
This function is just like `printf', except that the output is written
to the stream FID instead of `stdout'.
This is like `printf', except that the output is returned as a string.
In the first form, read from FID according to TEMPLATE, returning the
result in the matrix VAL.
This is like `fscanf', except that the characters are taken from the
string STRING instead of from a stream.
Read binary data of type PRECISION from the specified file ID FID.
Write data in binary form of type PRECISION to the specified file ID
FID, returning the number of values successfully written to the file.
Return the file ID corresponding to a new temporary file with a unique
name created from TEMPLATE.
Return the file ID corresponding to a new temporary file with a unique
name.
Return a unique temporary file name as a string.
Return 1 if an end-of-file condition has been encountered for a given
file and 0 otherwise.
Return 1 if an error condition has been encountered for a given file
and 0 otherwise.
Print a list of which files have been opened, and whether they are open
for reading, writing, or both.
Return the position of the file pointer as the number of characters
from the beginning of the file FID.
Set the file pointer to any location within the file FID.
Return the value required to request that `fseek' perform one of the
following actions:
`SEEK_SET'
Position file relative to the beginning.
Move the file pointer to the beginning of the file FID, returning 0 for
success, and -1 if an error was encountered.
