In DOS 3.2, one could specify DOS's environment space in the config.sys file with a line something like (I don't remember the exact syntax): SHELL=c:\command.com /e:512 (That may have been /p:512, I can't remember exactly). The point is that they changed it in DOS 3.3+!!!!!!!!!! And of course, the manual doesn't even mention the environment space (Working with Ms-Dos is like having a nickel shoved up ...). Does anyone know how to increase the environment space for DOS 3.3+? Pls email responses as I hate PC's and don't read the group. Thanks for the information!! -- Jason Coughlin ( jk0@sun.soe.clarkson.edu , jk0@clutx ) "Every jumbled pile of person has a thinking part that wonders what the part that isn't thinking isn't thinking of." - They Might Be Giants

Debug command.com, then display :0EB8 - this should be 0Ah. This is where COMMAND.COM stores the size of the environment table. Change it to whatever you want, and write the changes back to disk again. This has the nice advantage of taking no additional space or anything. However, it will only work for DOS 3.3. The way I got this address was by debugging command.com with the command line argument to increase environment space: debug command.com /e:256 And then tracing along until command.com parsed the command line. About the time it finishes reading the argument, it converts it from ASCII to hex and then writes it to :0EB8, overwriting the 0Ah default. Then I quit debug, restarted it, and changed the value. Works fine on my computer. The same process should work for 4.0 and above. -- -------------------------------------------------------------------------- | Randy Spangler | The less things change, the | | rspangle@jarthur.claremont.edu | more they remain the same | --------------------------------------------------------------------------
