<B>ENVIRON Modify Environment Table</B>
|
|
|
|
<B>ENVIRON</B> <U>stringexpr</U>
|
|
|
|
Adds a statement to or deletes a statement from the current
|
|
environment table.
|
|
|
|
<U>stringexpr</U> A string expression of the form "<U>name</U> = <U>parameter</U>".
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
<B>Notes:</B> If <U>name</U> already exists in the environment table, its
|
|
current setting is replaced with the new setting. If <U>name</U>
|
|
does not exist, the new statement is added at the end of
|
|
the environment table.
|
|
|
|
To delete an entry from the environment table, make
|
|
parameter a semicolon (i.e. "name = ;").
|
|
|
|
<U>parameter</U> is case-sensitive.
|
|
|
|
The new environment variable added, deleted, or modified
|
|
by this procedure will only take effect for SHELLed copies
|
|
of COMMAND.COM that are activated after this statement.
|
|
After the program exits, the environment table will be
|
|
exactly the same as before the program executed, no matter
|
|
what changes were made with ENVIRON.
