Why do I receive errors on running the ISHOW command at the debug prompt in Simulink 6.0 (R14)?

I open the 'vdp' Simulink model in the debug mode by typing the following at the MATLAB command prompt:

sldebug('vdp')

The model opens in the debug mode and I type the following at the debugger prompt:

ishow

I recieve the following error message:

 ??? Error using ==> sldebug

 Undefined function or variable 'ishow'.

I expect the ISHOW command to toggle the display of integration information as mentioned in the documentation page:

This bug has been fixed in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:

The ISHOW command has been deprecated as of Simulink 6.0 (R14). The documentation page needs to be updated to reflect this change.

As a workaround, you may use the STRACE command to set solver trace settings.

For more information on this command, type the following at the MATLAB command prompt:
