@b@cAbout


@bDescription

Displays a window with useful information about xldlas, including copying
policy, warranty (nada), ftp site locations, source code data, compilation
date, and so on.

 
@bNotes

The author's e-mail address should be used primarily to find out where to
send donations :)

@b@cLoad


@bDescription

Used to load in a file previously saved in xldlas's .lda format. If you
don't have reams of data lying around in this format then you'll have to
import ASCII data (see below) or input data by hand. The Load command erases
the dataset in memory, and so can cannot be used if there is unsaved (or
undropped) data.


@bNotes

If you have data that you want to get into xldlas, use the Import command.
It works, and it's safer than trying to hand build (or awk) .lda files.

@b@cSave


@bDescription

The save command will store all of the current variables, variable names,
variable descriptions, the dataset label, and the current value for a
missing observation in an xldlas's .lda format file. This file can later be
fed back into xldlas using the Load command.


@bNotes

The file format is very specific, so don't edit .lda files manually unless
you know what you are doing.

@b@cAppend


@bDescription

Append will load a new .lda file into xldlas without first erasing the data
in memory. This can be very useful for building large datasets out of
smaller ones. If a variable name in the dataset being appended exactly
matches the name of a variable already in memory, then that data will be
appended onto the end of the existing variable. If there is no name match, a
new variable is created with name taken from the file being appended.

@b@cImport


@bDescription

Import can read in space delimited ASCII data. The incoming file should
consists of nothing but float values seperated by whitespace and newline
characters. If you choose the columns option, then xldlas will create a
variable for each column present in the file and read subsequent data into
those variables. The row option will create a new variable for each line in
the file.

In both cases, any line which begins with a non numeric character 
(0-9, +, -) will be ignored. The routine uses ASCII codes to check
the first non-whitepsace character on each line, so if you're using
some operating system that does non-standard stuff vis-a-vis cahracter
codes you may have problems. If you do, please contact the author and
he'll try and figure out a solution.


@bNotes

As of v0.70, the import routines have been vastly improved. They are
virtually guaranteed not to fail (the author has succesfully imported
a Linux kernel image: meaningless data, but it didn't freeze xldlas).

@b@cQuit


@bDescription

This will exit xldlas. It can only be selected if there is no unsaved data
in memory. If you don't want to save the data, then drop it (see Data -->
Drop)


@bNotes

Unlike pushing the close window button, this menu option does not ask you if
you are sure you want to quit.
