[GREG2\]WRITE Item File_Name
[GREG2\]WRITE COLUMN File_Name [OLD|NEW [Format]] /TABLE [X Nx] [Y
Ny] [Z Nz]
This command is used to save some GreG internal buffers on an output
file for later processing. The item specifies what is to be saved, and
the format of saving, and can be :
POLYGON
Save the current polygon in a formatted way on two columns easily
readable by command COLUMN or POLYGON later. The default extension
is .POL
RGDATA
Save the current Regular Grid array on a RGDATA-like output file (to
preserve the result of a masking, or of a random mapping interpola-
tion). See also HELP RGDATA FILE_FORMAT. The default extension is
.DAT
IMAGE
Same as above but use the more efficient and complete IMAGE data
format of GILDAS. The default extension is .GDF
COLUMN (no option)
Save the current X Y Z buffers on a formatted output file (after a
SORT or a STRIP for example). The default extension is .DAT
COLUMN /TABLE
Save the X Y Z buffers but on column Nx, Ny, Nz of the specified
output table (Gildas Data Format). A new table is created if argu-
ment NEW is specified, otherwise the table must already exists (de-
fault OLD). The format of NEW tables can be specified as a 4th argu-
ment in REAL (default), DOUBLE or INTEGER. The OLD tables may be ex-
panded if any of Nx, Ny or Nz exceed the table column number ; exact
match on the number of lines is required. The tables can be read by
command COLUMN /TABLE.
