One of the new features of v13 is the GENERATE DIGEST command which allows the generation of MD5 and SHA1 digests - using this command we can easily compare two blobs to see if the are the same.

Here is the utility method for comparing two blobs using the GENERATE DIGEST command:

C_BOOLEAN($0) C_BLOB($1;$2) If (Count parameters=2)    $0:=(GENERATE DIGEST($1;MD5 Digest)=GENERATE DIGEST($2;MD5 Digest)) End if

If the code above is saved as aproject method named UTIL_Blob_Compare then it could be used like this:

C_BLOB($blob1;$blob2) If (UTIL_Blob_Compare ($blob1;$blob2))     // blobs are the same Else     // blobs are NOT the same End if
