errorDepth i -- sets the error depth to
i, which should be a small integer, returning the old value.
errorDepth() -- returns the current error depth.
During the backtrace after an error message, a position in interpreted code is displayed only if the load depth was at least as large at the time the code was parsed as the error depth is now. Typically, the error depth is set so that messages from code pre-interpreted and reloaded with
loaddata will not appear in the backtrace.
To increase the size of the stack trace, reduce the
errorDepth.
