 Hi Bart,

  Is there a way to pass in my own defined parameters to such a function?
 
  I would like to be able to do something similar to the following:
 
  \startCenteredText[myownparm=This is a test]
\startlines
 My own parm is: \myownparm
\stoplines
  \stopCenteredText

 Not with framedtext but you define your environment with a optional
 argument.

 ConTeXt has the command \definestartstop but it did not help in your case,
 something like LaTeXs \newenvironment, I wrote a simple version below.

 \unprotect

 \def\ev{ev}

 \def\environmentparameter#1%
   {\csname\ev\currentenvironment#1\endcsname}

 \def\defineenvironment
   {\dodoubleempty\dodefineenvironment}

 \def\dodefineenvironment[#1][#2]%
   {\getparameters
  [\ev#1]
  [\c!before=,
   \c!after=,
   #2]%
\setvalue{\e!start#1}{\dodoubleempty\dostartenvironment[#1]}%
\setvalue{\e!stop #1}{\dostopenvironment}}

 \def\setupenvironment
   {\dodoubleargument\dosetupenvironment}

 \def\dosetupenvironment[#1][#2]%
   {\getparameters[\ev#1][#2]}

 \def\dostartenvironment[#1][#2]%
   {\bgroup
\edef\currentenvironment{#1}%
\ifsecondargument
  \setupenvironment[\currentenvironment][#2]%
\fi
\environmentparameter\c!before}

 \def\dostopenvironment
   {\environmentparameter\c!after
\egroup}

 \protect

 \defineframedtext
   [CenteredTextFrame]
   [width=fit,
location=middle]

 \defineenvironment
   [CenteredText]
   [before=\startCenteredTextFrame\startlines,
after=\stoplines\stopCenteredTextFrame]

 \starttext

 \startCenteredText[text={This is a test}]
 My own parm is: \environmentparameter{text}
 \stopCenteredText

 \stoptext


Thanks Wolfgang for the insight.

 Here is one that did exactly you wrote, nothing else.

 \defineframedtext[CenteredTextFrame][width=fit,location=middle]

 \def\startCenteredText
{\dosingleempty\dostartCenteredText}

 \def\dostartCenteredText[#1]%
{\bgroup
 \iffirstargument
   \def\docommand##1{\getparameters[][##1]}%
   \processcommalist[#1]\docommand
 \fi
 \startCenteredTextFrame}

 \def\stopCenteredText
{\stopCenteredTextFrame
 \egroup}

 \starttext

 \startCenteredText[myownparm=This is a test]
\startlines
   My own parm is: \myownparm
\stoplines
 \stopCenteredText

 \stoptext

Yes, a much simpler solution, but I appreciate having both.

Thanks,
Bart

In analogy to \framedtext after a define of a framedtext I expect  
that that you should use \CenteredText{...}

And indeed.

\defineframedtext[CenteredText][width=fit]
% This one fails!
\startalignment[center]
\dontleavehmode
\CenteredText{
\startlines
