global function bug_free_library_function(integer i1) 
      integer i2 
      i2 = trace_level() 
      -- function code here 
      i1 = 0 
      -- now restore the previous trace level, just before return 
      trace(i2) 
      return "success!" 
end function         
 
procedure my_buggy_proc() 
      sequence s1 
      integer i1 
      trace(1) 
      -- my buggy code here.. 
      i1 = 0 
      -- then a standard library call where I don't need trace on... 
      s1 = bug_free_library_function(i1) 
      -- the rest of my buggy code here 
end procedure 
 

This is not really practical because we are not going to add 'trace_level' to every standard library function just so users can avoid tracing through them.

However, you do know that you can press the down-arrow to avoid tracing through a function call?

The idea you suggest has some merit but I'd like to do it slightly differently. Let's make the trace() call a function instead. It can return the current trace level while setting a new level, and because we no longer have to use a function's return value, current code would not be affected.

global function bug_free_function(integer i1) 
      integer i2 
      i2 = trace(0) -- turn any tracing off 
      -- function code here 
      i1 = 0 
      -- now restore the previous trace level, just before return 
      trace(i2)  
      return "success!" 
end function         
 
procedure my_buggy_proc() 
      sequence s1 
      integer i1 
      trace(1) 
      -- my buggy code here.. 
      i1 = 0 
      -- then a library call where I don't need trace on... 
      s1 = bug_free_function(i1) 
      -- the rest of my buggy code here 
end procedure
