Isn't there a limit to the number of characters in a DOS command?  I
thought it was 127 or 128.  This implies that no matter what you do,
you won't be able to execute a long command even to COMMAND.COM.
when you type it to a COMMAND.COM window?

Even if this limit has been enhanced under Win Me/9x, it's possible
that IDL is using some older, more limited version of the interface.
