Features


Text Search/Replace
Hex Search/Replace
Text wildcard Search & Replace
e.g. HEL? would find all words that begin with "HEL"
e.g. HE?P would find all words that begin with "HE" and end with P


Hex Pattern Wildcard Search & Replace
e.g. 55??AA would find all Hex patterns that start with 55
then an unknown hex value followed by AA
e.g. 55??AA??BB would find all Hex patterns that start with 55 then an unknown hex value followed by AA then an unknown hex value followed by BB

The Replace feature utilizes wild card capability and flexibility where unknown values remain unchanged and only values explicitly stated will be updated/changed.
e.g. Replace 65??45 would replace the 1st byte with 65 the 2nd byte will remain unchanged and the 3rd byte changed to 45

** The Hex wildcard now supports 4Bit hence two(2) '??' is required to represent one 8Bit hex unknown **
