SCREEN - Position the cursor and display text
Purpose: Position the cursor on the screen and optionally display a
message.
Format: SCREEN row column [text ]
row : The new row location for the cursor.
column : The new column location for the cursor.
text : Optional text to display at the new cursor location.
See also: ECHO, SCRPUT, TEXT, and VSCRPUT.
Usage
SCREEN allows you to create attractive screen displays in batch files.
You use it to specify where a message will appear on the screen. You
can use SCREEN to create menus and other similar displays. The following
batch file fragment displays a menu:
@echo off
cls
screen 3 10 Select a number from 1 to 4:
screen 6 20 1 - Word Processing
screen 7 20 2 - Spreadsheet
screen 8 20 3 - Telecommunications
screen 9 20 4 - Quit
SCREEN does not change the screen colors. To display text in specific
colors, use SCRPUT or VSCRPUT. SCREEN always leaves the cursor at the
end of the displayed text.
The row and column values are zero-based, so on a standard 25 line by 80
column display, valid rows are 0 - 24 and valid columns are 0 - 79. You
can also specify the row and column as offsets from the current cursor
position. Begin the value with a plus sign [+] to move the cursor down
the specified number of rows or to the right the specified number of
columns, or with a minus sign [-] to move the cursor up or to the left.
This example prints a string 3 lines above the current position, in
absolute column 10:
screen -3 10 Hello, World!
If you specify 999 for the row, SCREEN will center the text vertically on
the display. If you specify 999 for the column, SCREEN will center the
text horizontally. This example prints a message at the center of the
display:
screen 999 999 Hello, World
SCREEN checks for a valid row and column, and displays a "Usage" error
message if either value is out of range.
