Examples doskey Starts doskey and allows you to press the up or down command to see history, or right or left to retype previous command. Technical support Specifying a buffer size larger than 61900 for DOSKEY causes the computer to freeze. DOSKEY supports approximately 61900 bytes. Due to an error in the DOSKEY program that causes DOSKEY to mark memory as unused when it terminates and stays resident, specifying a buffer size larger than this amount causes the computer to hang. |
