The input file must be organised in a Table-like way, with formatted
numbers arranged in column and lines. GREG uses list-directed format to
read this file, so that the numbers need only be separated by spaces, tabs
or commas. However, a single complete logical line of the table must be
contained in a logical record of the input file. Any column, and any range
of lines, can then be accessed typing
COLUMN X Nx Y Ny Z Nz [/FILE Infile] [/LINES Lmin Lmax]
where Nx is the column number from which the X buffer is to be read (resp.
Ny and Nz), Infile is the input file name, and Lmin Lmax define the range
of lines to select. By default, the last connected file is used. Changing
the input file resets Lmin and Lmax to select the complete file. The order
of the X Y Z keywords is not compulsory, and some may be missing ; however
each keyword must be immediately followed by its associate column number.
There is an implementation dependent limit (usually 50000) on the number of
lines that can be read by one COLUMN command in a formatted file. To go
over that limit, you can convert the formatted file to a table (usually a
good idea), or work by pieces using /LINES.
