Unsetting a variable ( en )

Last modification : 2013/01/26 19:16
In MSH.EXE variables are available everywhere and every time. But it is possible sometimes to delete a variable from the environment with the unset command.

The syntax is: unset variablename 
msh> set A=123
msh> print $A
123
msh> unset A
msh> print $A
