SEARCH.CO by Paul Globman
Copyright (c) 1985,1989
To create SEARCH.CO just run the BASIC loader.
SEARCH.CO will find the locations of a defined byte sequence and display the
addresses where the sequence is found.
To use SEARCH.CO you must run a small basic program which defines the byte
sequence. Such a program may be as simple as...
1 LOADM"SEARCH"
2 INPUT"Find";X$
3 CALL 63900,,VARPTR(X$)
This is fine if the string you are searching for is an ASCII string that can be typed in at the keyboard.
Suppose you are looking for all occurrences of CALL 20353. Then line 2
would be...
2 X$=CHR$(205)+CHR$(20353MOD256)+CHR$(20353\256):REM CHR$(205)=CALL(op code)
Other variations of line 2 can be used to define the sequence of bytes you
want to search for. For example GOSUB 4, where you would define a subroutine
to generate X$, using DATA statements or an input loop.
SEARCH.CO will examine all of memory, from address 0 to address 65535, and
will display locations of exact matches as:
in xxxxx in xxxxx in xxxxx in xxxxx
where xxxxx is the decimal address of the matched byte sequence.
