I keep command.com in a directory I call "systm", and have the following line in my config.sys file: shell=c:\systm\command.com c:\systm /P /E:32 which tells the MS-DOS startup routines where to find command.com on boot-up (the first entry), where to find it for reloading, if need be (the second entry), makes this permanent (the /P) and sets aside 32 paragraphs of environment space (I'm using DOS 3.1. For DOS 3.3 you would use E:512 to set aside 512 bytes, the same as 32 paragraphs. This change is brought to you by the Upward Compatibility Group at Microsoft, at no extra charge whatsoever.). -- Ed Nather Astronomy Dept, U of Texas @ Austin
