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.
* TRACE var::
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)
