there is no such macro. The points are handled on PostScript
level, but the value fpr the parbox on LaTeX level. You can
pass values from LaTeX->PostScript but not vice versa.

However, there is \psTextFrame. Maybe it helps:

\documentclass{article}
\usepackage{pstricks}
\begin{document}
	
\begin{pspicture}[showgrid](0,-0.5)(10,10)
\psTextFrame[linecolor=lightgray,ref=l](0,0.5)(4,1.5){Hallo}
\psTextFrame[linecolor=blue](2,4)(4,7){\color{blue}Hallo}
\psTextFrame[linestyle=dashed](9,9)(10,10){\huge H}
\psTextFrame*[linecolor=red,linestyle=dashed](7,7)(9,9){\Huge H}
\psTextFrame*[linecolor=red!40,ref=lB](7,4)(9,6){\Huge H}
\psTextFrame*[linecolor=blue!40,ref=rt](7,1)(9,3){\Huge H}
\psTextFrame[linestyle=dashed](4.5,0)(6.5,10){%
   \parbox{2cm}{\centering Here comes some more text over
	several	lines, which is also horizontally and vertically
	centered and written in a parbox.}}
\psTextFrame*[linecolor=cyan!20,rot=90](.5,2)(1.5,10){%
	\parbox{8cm}{\centering Here comes some more text over
		several lines and rotated by 90 degrees.}}
\end{pspicture}
	
\end{document}
