This allows PRINT and ? to give the same checksum value. If long lines require Basic keywords to be abbreviated, the checksum value will still be correct. Spaces matter only if they are within quotes. Transposition errors are caught<br /> <br /> ML Perfect Typist is for machine language programs and has 13 pairs of characters per line, with the last two pairs acting as a checksum.<br /> <br /> <br /> == Sample Output ==<br /> [[File:Perfect Typist.jpg]] Perfect Typist<br /> <br /> [[File:ML Perfect Typist.jpg]] ML Perfect Typist<br /> <br /> <br /> == Links ==<br /> * [https://archive.org/details/run-magazine-21/page/n79/mode/2up 64 Perfect Typist] (Run Sep 1985 pg 78)<br /> * [https://archive.org/details/run-magazine-24/page/n111/mode/2up 128 Perfect Typist] (Run Dec 1985 pg 110)<br /> * [https://archive.org/details/run-magazine-24/page/n51/mode/2up ML Perfect Typist] (Run Dec 1985 pg 50)<br /> * [https://archive.org/download/run-magazine-36/Run_Issue_36_1986_Dec.pdf ML Perfect Typist 2.0] (Run Dec 1986 pg 98)<br /> * [https://archive.org/details/run-magazine-rerun-disks Perfect Typist in .d64 format]<br /> ** 64 Perfect Typist in [https://diskmaster.textfiles.com/browse/7121/rerun-1985-winter.d64 rerun-1985-winter.d64]<br /> ** 128 Perfect Typist and ML Perfect Typist in [https://diskmaster.textfiles.com/browse/7122/rerun-1986-01-02.d64 rerun-1986-01-02.d64]<br /> ** ML Perfect Typist 2.0 in [https://diskmaster.textfiles.com/browse/7127/rerun-1986-11-12.d64 rerun-1986-11-12.d64]</div>
