You can save the current screen image to disk by selecting the Save Screen
to Disk option from the File menu. The Save Screen to Disk dialog box appears.

Select the appropriate directory, enter a valid filename, and click on
OK to save the screen image to disk. The image is usually appended to the
file, unless you have selected to overwrite it in the Save category.
The Save As option lets you save the image using the ASCII (for DOS) or
ANSI (for Windows) character sets. The option is useful if you have characters
with accents, such as ä. The Save Mode option allows you to overwrite or
append the data to an existing file.
