How many elements were created by split()? When I do a split on a field, e.g., {{{ awk split($1,x,"string") }}} How can i find out how many elements x has (I mean other than testing for null string or doing a `for (n in x)' test)? split() is a function; use its return value: {{{ awk n = split($1, x, "string") }}}
Summary:
This change is a minor edit.
