Does anyone know how to insert a postscript file in TeXture 1.2?

In VAX I usually put a following command (\insertplot) in my LaTeX file.

   \begin{figure}
   \insertplot{tz.ps}{4.8}{7.5}{0}{3}{0.8}
   \caption{Time-averaged distribution of vertical position for stored muons.}
   \label{tz}
   \end{figure}

and put an appropriate postscript file in the same directory.
I also have a INSETPLOT.TEX (shown below) file to interpret the command 
(\insetplot).  I did exactly do the same thing for Mac and it didn't work.
Any help would be greatly appreciated.   Thanks.

% Insertplot parameters:
%	#1: name of user-generated postscript file
%	#2: figure height (inches)
%	#3: figure width (inches)
%	#4: lower left x-coordinate of figure (inches from left side)
%	#5: lower left y-coordinate of figure (inches from bottom)
%	#6: desired figure magnification (1.000 = unmagnified)
%
% Parameters 2-5 refer to the magnified dimensions of the plot as 
% printed when the user-generated PostScript file is submitted "as-is" 
% to the PostScript printer, not to the dimensions you wish it to have
