messageBox [text,nButtons]

Returns ID of pressed button

Shows message box with text and buttons.

nButtons is undocumented but probably follows the msoft conventions of ok, cancel, blah, + warning icons

nButtons 0: == OK only

isnil

example:

 if (isnil "_exists") ExitWith(_file_exists=false;};

 if (!isnil "_exists") ExitWith(_file_exists=true;};

note that exitwith is pretty close to useless it ONLY breaks out of the current braces, not, out of a subroutine per se

nil

example:

 _dirs= shellCmdOpenPipe("....
{
  process...
}
_dirs=nil;
