constr from optimization toolbox

I'm a beginner regarding Matlab, but for my work I try to get an old program running which was written in 1997 in Matlab. Unfortunately I have quite some problems get this running in a current Matlab version. It has been working fine as it is 25 years ago, that much I know.

Where I'm stuck at the moment is this line:

[Xopt,opt] = constr('kropt', xstart, options, Vlb, Vub, [], NU, 1, cymma);

Here I get the error message, that the command "constr" is not found, or invalid. According to the comments in the code it is supposed to be from the Optimization TB. Has this command been replaced by something else? Or can anybody give me a hint what the problem might be?

Thank you in advance
