The "parameter*=x" works to make the parameter visible but the user is not allowed to change it.
However, any suffix entered appears on the next line.
Also, the "keep next parameter on the same line" does not work properly. For example, if 2 parameters have the * and the first one has "keep next" checked, then the name for the second parameter does not appear and the the second parameter is not on the same line as the first parameter.
Thanks for your help.
