    // TTT is stopped until the return-key is pressed, if printlevel>0.
    // xxx may be any result of a previous computation or a comment, etc:
    //
    // proc TTT
    // { int pp = printlevel-voice+2;  //pp=0 if printlevel=0 and if TTT is
    //    ....                         //not called from another procedure
    //    if( pp>0 )
