Enables echoing of NCL statements as they are encountered.
procedure echo_on ( )
Echoes NCL statements as they are encountered. This can be particularly useful when debugging NCL scripts in batch mode. This procedure has the same effect as the command line option -x and is useful in conjunction with echo_off.
Turn on echo mode to debug a script. Echoing of commands will occur until the end of the script.
begin [...] x = 0 [...] echo_on() if (x .eq. 0) [...] end if [...] end
