1) awk with RS set to ) doesn't break records at line ends but on occurrences of the RS char / pattern. So, the first record (also referred to as $0 in awk) is
Code:
 process(130

, which is split in two at the field separator FS=\(.
Code:
$0=$2

then overwrites the entire record with its second field, and, because used as an awk-pattern not equal 0 (= TRUE), takes the default action print.

2) Your echotext is corrupted in your post as the second left parenthesis is missing. The sed substitutes the BRE
Code:
^               start of line
.*(             (.) any character (*) zero or more times up to a left parenthesis
\([^)]*\)       first sub-expression (delimited by escaped! parentheses): zero or more non-right-par.
).*(....        next right par. followed by any char zero + times, then left par., then any four chars
\(.*\)          second sub-expr.: any chars zero or more times
).*'            next right par. followed by any char 0+ times, then apostrophe (single quote)
\(.*\)          third sub-expr.: any chars 0+ times
'.*             rest of line starting from apostrophe

by first sub-expr. space second sub-expr. space third sub-expr.
