If you look closely, you'll find, that the working string S will never be longer than the longest line of the input file plus 63. The script adds one line to S and then writes 64 character portions to the output file until S is shorter than 64 characters.

The easiest way would be to use the base64 utility from the GNU coreutils, because it does not care about the proper 64-character-linelength, but it is not available everywhere.
