1. trace() enhancements (was Re: request for 2.5)
Rob,
I was toying with the idea of doing this:
prevtrace=tracef(0)
<code never to be traced>
trace(prevtrace)
Do you think a new builtin function tracef would be a good idea?
I also tried the following code as a partial proof of concept:
without trace
integer myPrevTrace
myPrevTrace=0
procedure myTrace(integer t)
myPrevTrace=t
trace(t)
end procedure
function myTracef(integer t)
integer p
p=myPrevTrace
myPrevTrace=t
trace(t)
return p
end function
with trace
integer i,prevtrace
myTrace(1)
i=1
prevtrace=myTracef(0)
i=2
myTrace(prevtrace)
i=3
but the trace never triggered. If I replace the without trace on line
1 by with trace, it does actually work as expected, namely not
stopping on the i=2 line, apart from five unwanted stops in myTrace &
myTraceF, which is why I decided to propose a new builtin.
Regards,
Pete
