24 This a shell built-in command that causes the process executing the
|
|
|
25 shell to start execution of another program. It permits a transition
|
|
|
26 from the shell to another program without creating another process,
|
|
|
27 thus conserving system memory.

30 This command is often used when the shell is called from another
|
|
|
31 program to execute a specific program, after which the shell is not
|
|
|
32 needed. For instance, applications which only use BASIC09 need not
|
|
|
33 waste memory space on SHELL.

36 The "ex" command should always be the last command on a shell input
|
|
|
37 line because any command line following will never be processed.
