<h1><a name="kap_interrupt_3030"></a>INT 2E - Execute Command
Using Base Level Command Interpreter (Undocumented DOS 2.0)</h1>
<p> DS:SI = pointer to command string to be executed</p>
<p> returns nothing ???</p>
<p> - causes the base level COMMAND.COM to execute a command as
if it</p>
<p> were typed from the keyboard</p>
<p> - the transient portion of COMMAND.COM must be loaded if not
resident</p>
<p> - first byte of the string contains the string length,
inclusive</p>
<p> - command string must be terminated with a CR</p>
<p> - all registers including SS &amp; SP are destroyed; SS &amp;
SP should be</p>
<p> preserved in your own code segment</p>
<p> - can be used to modify parents environment with SET command</p>
<p> - incompatible under some software multitasking systems</p>
<p> - before returning to the parent program this interrupt will</p>
<p> attempt to execute the &quot;current&quot; batch file (if the
parent or</p>
<p> any ancestors were invoked from a batch file. This can cause</p>
<p> remaining lines in a batch file to execute before the parent</p>
<p> program finishes and fragment memory</p>
