3.10.1 Tracing of procedures

Setting the TRACE variable to 1 (resp. 3) results in a listing of the called procedures (resp. together with line numbers). If TRACE is set to 4, Singular displays each line before its interpretation and waits for the <RETURN> key being pressed.

5.3.9 TRACE

See TRACE var.

Example:

  proc t1
  {
    int i=2;
    while (i>0)
    { i=i-1; }
  }
  TRACE=3;
  t1();
→ 
→ entering t1 (level 0)
→ {1}{2}{3}{4}{5}{4}{5}{6}{7}{4}{5}{6}{7}{4}{6}{7}{8}
→ leaving  t1 (level 0)
