During INPUT, CTRL+T Displays Softkeys on Line 25
Last reviewed: January 12, 1995

Article ID: Q46849

SUMMARY
During an INPUT statement, pressing CTRL+T causes a number line to display on line 25 of the screen. These numbers correspond to the softkeys that you can define and label with the KEY statement in Basic. This behavior is not documented and occurs in all screen modes.

This information applies to Microsoft QuickBasic Versions 4.00, 4.00b, and 4.50, to Microsoft Basic Compiler Versions 6.00 and 6.00b, and to Microsoft Basic PDS Version 7.00.

MORE INFORMATION
To prevent this behavior, you can trap for CTRL+T using the KEY statement. The key combination is trapped during the INPUT statement but is not acted upon until after the INPUT statement is terminated. This delay allows you to trap for the key and simply RETURN from the label.

The following sample code prevents display of the softkey line during the INPUT of the string:

KEY 15, CHR$(&H04) + CHR$(&H14)    'delete these lines KEY(15) ON                         'to see the softkey ON KEY(15) GOSUB KeyPressed        'display during input

PRINT &quot;hit CTRL+T then,&quot; PRINT &quot;enter a string&quot; INPUT AnyString$ END

KeyPressed:

RETURN
