The $bfind identifier is used to find a matching value in a binary file.
<nowiki>$bfind(&binvar,N,M)</nowiki>
Returns the position of the first matching character.
''N'' is the starting position for the file.

''M'' is the matchtext, it can contain plain text or [[$asc|ascii]] values. The search is case-insensitive.

use $bfind().text to force a plain text search, in case your text is a number.

== Examples ==
[[bset]] -t &test 1 ABC 97 abcd
[[echo]] -a [[$bvar]](&test,1,$bvar(&test,0)) returns ''65 66 67 32 57 55 32 97 98 99 1000''
echo -a $bfind(&test,1,a)
We searched for an "a", but as the match is case-insensitive, the A matches too. The last echo will echo ''1'' as an "a" is at position 1.

bset -t &test 1 ABC 97 abcd
echo -a $bfind(&test,1,97) returns ''8''
echo -a $bfind(&test,1,abcd) returns ''8''
echo -a $bfind(&test,4,a) returns ''8''
In the first echo, we only search for character 97, wich is an "a", but this time "A" won't match.
In the second echo, we search for "abcd", wich is only found at the end of the var.
In the third echo, we search for "a", but we start searching at position 4, so the "A" won't be found.

bset -t &test 1 ABC 97 abcd
echo -a $bfind(&test,1,97).text returns ''5''
We now searched for the text "97" and not character 97.
