Thank you all for your replies!

In response to Don's questions: This input file...
Code:
@LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0 
@LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0 
@LIB ADVAPI32.dll @CAL BlaCall @PA1 0x0012f741 @PA2 0x0012f68c @PA3 4 @RET 0x0012f8bc 
@LIB ADVAPI32.dll @CAL memmove @PA1 0x0012f740 @PA2 0x0012f68c @PA3 4 @RET 0x0012f8bc 
@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS

...should turn into this (minimal "destruction"):
Code:
@LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0 
@MATCH
@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS

If there are more than 3 newlines in between the first and second part of the pattern, nothing should happen. The replacement should only be executed as long as the "maximum gap" is not exceeded (in this case 3). So if the input file would look like this:
Code:
@LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0 
@LIB ADVAPI32.dll @CAL memmove @PA1 0x0012f740 @PA2 0x0012f68c @PA3 4 @RET 0x0012f8bc 
@LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0 
@LIB ADVAPI32.dll @CAL BlaCall @PA1 0x0012f741 @PA2 0x0012f68c @PA3 4 @RET 0x0012f8bc 
@LIB ADVAPI32.dll @CAL memmove @PA1 0x0012f740 @PA2 0x0012f68c @PA3 4 @RET 0x0012f8bc

@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS
@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS
@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS
@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS
@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS
@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS

@LIB ADVAPI32.dll @CAL memmove @PA1 0x0012f740 @PA2 0x0012f68c @PA3 4 @RET 0x0012f8bc

...the script should NOT replace the large block of "RtlAnsiStringToUnicodeString".

Thanks again!

       otherwise only the file, family and style are printed..

       below.

       -v --verbose
	      Print whole font pattern for each match.

       -? --help
