Singular Manual: printlevel

  | ### 5.3.6 printlevel `Type:` int `Purpose:` sets the debug level for `dbprint`. If `printlevel` >= `voice` then `dbprint` is equivalent to `print`, otherwise nothing is printed. `Note:` See Procedures in a library, for a small example about how this is used for the display of comments while procedures are executed. `Example:`
        voice;
      ==> 1
        printlevel=0;
        dbprint(1);
        printlevel=voice;
        dbprint(1);
      ==> 1
See dbprint; int; voice.
