In the future, please always tell us what operating system and shell you're using when you start a thread in the Shell Programming and Scripting forum, and, when you get a syntax error, please show us the actual diagnostic message that you get when you try running your code.

In this case, I would guess that your problem is that standard implementations of awk do not include an elif clause in an if statement. If you change the elif in this case to else if:
Code:
echo "some output" |
awk '{	for(i=1;i<=NF;i++){
		if($i ~ /patternA/){
			print $i, $(i+1)
		} else	if($i ~ /patternB/){
				print $i
			}
	}
}'

you might get what you want, although nothing will be printed by your sample code given the input you are providing to your awk script.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
