Export to ASCII format
The program performs spectra export to files in ASCII format.
icon: 
menu: File | Export ASCII...
Spectra container dialog box:   
This operation is done through dialog window for saving disc files; it allows the
selection of a file format (extension), declaration of a file name and choosing of a
desired directory.

Format "*.dat": - file contains one column with counts in channels
Format "*.lst":  - file contains name of program Tukan8k, date of export,
name of spectrum and two columns of data: number of channel and number
of counts
Format "*.tab": - file contains name of program Tukan8k, date of export,
name of spectrum and spectrum in rows with 10 columns each. This format
support export of whole spectrum or only part of its
File ASCII formats
1.
"*.lst"
- (one column contains counts in channels values only) 
2.
"*.dat"
- (number of channel and counts in channels  values are placed
in two columns)
3.
"*.tab"
-  (counts in channels values are placed in ten columns )

Import from ASCII format
The program performs function of importing spectra saved to files in ASCII format
described in 
Export to ASCII format
, i.e."lst", „dat", „tab" and „rpt" (report files)
type.

menu: File | Import ASCII...
When performed, the "import spectra" dialog window is displayed containing
textual description of procedure concerned with importing data from ASCII files.
As described there, to the program can be imported data from any ASCII file, not
necessary saved in the formats described earlier
The „import spectra" dialog window is divided into two parts: upper displaying
plain contents of ASCII file from which data is being imported and bottom,
containing data as processed by the program. Based on that data, after selecting
the „Import" key, the program creates a spectrum (in „wdm" format) and places it
in the spectra container. When quitting the program, such a spectrum will not be
saved. If needed to be saved in „*.wdm" format, the user must run appropriate
command.
"Instruction" button will open detiled instruction how to proceede in case of the
other file formats:

Adding and subtraction spectra
Adding and subtraction operations are available from the same dialog window.
This window is accessible only form modules ANALYZER or ANALYZE from
menu Analyze.
Adding and subtraction spectra:
icon:  
menu:  Add /Subtract spectra...
Spectra (S1 and S2) for adding or subtraction may come from the 
Spectra
container
.
Mathematical operation is done based on the formula: (S1 * A + C) +/- (S2 * B).
A and B factors and C constant are taken from described opropriate edit fileds.
C constatant is used only if option "Add constatant value C" is checked. 
All operations are processed in float numbers but final results are rounded to
integers, negative numbers are zeroed.
Operation is done after press: Add or Substract. Program automaticly
generates description of result spectrum contining information after done
operations (with values of parameters), this description may be edited. Name
of the result spectrum is also generated and also may be changed before save
or later in the dialog window 
spectrum information
. 
Result spectrum is stored in memory after pressing OK button.

Compressing spectra
Operation of the spectrum compression may be run only in modules
ANALYZER or ANALYZIS.
Compressing spectra:
icon:  
menu:  Analysis | Compressing...
Operation consists in adding of counts in 2, 4 or 8 following channels and
storing results in the new spectrum.

Printing a spectrum
Each spectrum (or their composition), is displayed on the screen can also be
printed:
icon: 
menu: File | Print spectrum...
This operation opens a dialog window showing a print preview and allowing
printer selection and setting printing parameters. The spectrum is printed in the
same shape as in the preview (all printing colors are identical if available on the
printer).

It is recommended, for printing speed reasons, to display a spectrum in the line
segment plotting style.
More advanced printing options are available in the  REPORTS module.

Plotting a spectrum
A spectrum is displayed in the special panel, which has spectra scrolling bars
(vertical and horizontal) and buttons for changing of the scaling range. Using
keyboard or mouse you can see any fraction of the spectrum enlarged to
required level. Both scrolling bars are joined in the bottom right corner of a panel
by a # button 
, which restores the display of the full spectrum.
To change the spectrum scale and its plotting style:
move the markers controlled by a mouse directly on the displayed
spectrum (
zoom
), 
click the appropiate icon on the toolbar:
choose a command from context menu of the display panel:
choose a command from the Screen menu:
use the 
keyboard
.
Before displaying, the spectrum is updated and display scale is automatically
adjusted to vertical and horizontal spectrum maxima (in the Y-axis there is 20%
margin left above the highest point). The same applies to the 
“live” spectrum”
when 
Y scale auto
 is turned on.
Displaying energy scale:
If the spectrum has energy calibration then in the field of the spectrum plot two
horizontal scales are displayed: bottom scale in channels units (black color),
