And now the second tool MakeCARR. It will do the whole thing in an array on C/C++ level, rather then in DATAs on the BASIC level. Although it's handling is a bit more tricky, as you get not only a .bm file, but also a .h file, and both must match (ie. the DECLARE LIBRARY path in the .bm must point to the .h), this approch has several advantages especially for big files:
Unless DATAs, which are included in the final EXE as written (ie. as ASCII chars), a C-Array containing numbers is embedded as (you guess) array of binary numbers, hence even uncompressed it would not take more space than the original file. This makes the compression even more valuable, as it really reduces the final EXE size, instead of just compensating the Number-to-Ascii bloat only as for the DATAs.


As the array is stored as successive numbers in memory, it's possible to write back the entire array with just one disk access, which is much faster than reading all single DATAs and concatenate them into one big string, which is then written out.


As the converted data is not in the included .bm file anymore (but in the .h file now), the syntax checking/compiling in the IDE will need less, depending on filesize much less time to finish, as it doesn't need to check 100s (or even 1000s) of DATA lines.


On C/C++ level it's easy to expand the given writeback path/filename into a full qualified absolut path using a standard library call. This path/filename is returned through the writeback function and can be used in your program to always safely access the written file, doesn't matter how often you change the current working directory using the CHDIR statement.


For any files, which are only needed temporarily during program runtime you can specify an auto-cleanup, which automatically deletes the written file again, as soon as your program terminates. This feature is also easily accessible on C/C++ level through an 'atexit()' function.



Again, if you're using at least QB64 v1.4 or any Phoenix Edition version and don't wanna use the extra Lzw packer libarary, but the QB64 built-in zlib compression instead, then simply substitute the LzwPack$ call (line 98) with the respective _DEFLATE$ call and the LzwUnpack$ call (line 312) with an _INFLATE$ call. Also delete the $INCLUDE line at the end.
