First, I think you should split this thread into the Underground forum, for instance, and link to it Smilie

Second, Kerhnighan *is* the author of nawk. What Solaris did to what they call nawk is anyone's guess.

Third, Solaris lists the nawk man page and xpg4/awk man page as the same entity (yet oddly, the files differ vastly in size).

Fourth, nawk explicitly errors with length(arrayname):
Code:
$ nawk 'BEGIN { split("test",out,/es/); print out[1]; print length(out)}' </dev/null
t
nawk: can't read value of out; it's an array name.
 source line number 1

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME
colrm -- remove columns from a file SYNOPSIS
colrm [start [stop]] DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read from the standard input. Output is written to the standard output. If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec- ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not zero. Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one. ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7). EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs. SEE ALSO
awk(1), column(1), cut(1), paste(1) HISTORY
The colrm command appeared in 3.0BSD. BSD
