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

i am still wondering.
|foo=content
|export foo
|or foo=$foo gawk ..
|gawk -vv=foo ' BEGIN { v = ENVIRON[ v ] } other code '

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