If your using hash tables, you can handle multiple spaces by using &binvars and /hadd -b
Again on binvars, the recent change to allow binvars to be any length (limited only by your systems resources) means you can /hadd -b and $hget(<table>,<item>,<binvar>) binary strings of any length.
//bset &test $calc(100*1024*1024) 0 | echo -a $bvar(&test,0) | hadd -smb test test &test | echo -a $hget(test,test,&test)
Of course, parsing/displaying those strings is another matter
