28Used to load in a file previously saved in xldlas's .lda format. If you
29don't have reams of data lying around in this format then you'll have to
30import ASCII data (see below) or input data by hand. The Load command erases
31the dataset in memory, and so can cannot be used if there is unsaved (or
32undropped) data.

37If you have data that you want to get into xldlas, use the Import command.
38It works, and it's safer than trying to hand build (or awk) .lda files.

51The save command will store all of the current variables, variable names,
52variable descriptions, the dataset label, and the current value for a
53missing observation in an xldlas's .lda format file. This file can later be
54fed back into xldlas using the Load command.

59The file format is very specific, so don't edit .lda files manually unless
60you know what you are doing.

73
74Append will load a new .lda file into xldlas without first erasing the data
75in memory. This can be very useful for building large datasets out of
76smaller ones. If a variable name in the dataset being appended exactly
77matches the name of a variable already in memory, then that data will be
78appended onto the end of the existing variable. If there is no name match, a
79new variable is created with name taken from the file being appended.

97Import can read in space delimited ASCII data. The incoming file should
98consists of nothing but float values seperated by whitespace and newline
99characters. If you choose the columns option, then xldlas will create a
100variable for each column present in the file and read subsequent data into
101those variables. The row option will create a new variable for each line in
102the file.
103
104In both cases, any line which begins with a non numeric character
105(0-9, +, -) will be ignored. The routine uses ASCII codes to check
106the first non-whitepsace character on each line, so if you're using
107some operating system that does non-standard stuff vis-a-vis cahracter
108codes you may have problems. If you do, please contact the author and
109he'll try and figure out a solution.

114As of v0.70, the import routines have been vastly improved. They are
115virtually guaranteed not to fail (the author has succesfully imported
116a Linux kernel image: meaningless data, but it didn't freeze xldlas).

130This will exit xldlas. It can only be selected if there is no unsaved data
131in memory. If you don't want to save the data, then drop it (see Data -->
132Drop)
