i fail to see what this has to do with my problem.

 |my='a b c'
 |# one line string
 |awk 3<<<"$my thing' BEGIN { f = "/dev/fd/3" ; getline v <f ; close( f ) }

i am still wondering.

 |foo=content
 |export foo
 |or foo=$foo gawk ..
 |gawk -vv=foo ' BEGIN { v = ENVIRON[ v ] } other code '
 |same as v = ENVIRON[ "v" ] or "varname"

wow.

 |to match in string , thers two ways , one is exact text match , the other

 |
 |if u /foo/ thats a regex

really?

 |$0 ~ "foo"
 |
 |tx=" my text "
 |if ( $0 ~ "pre" tx "stu" ) { ye }

this does not work the way you think maybe?
I surely was there myself.

 |thers additional stuff to say containing substr() and match() , and some

even with match() not (in a global match line).

 |others
 |
 |#exact
 |etx = " exact "
 |if ( index( $0 , etx ) ) { ye }
 |if ( index( $0 , "pre" etx "stu" ) ) { ye }

i am really impressed.
But that did not work out.
