01 文獻
Add MS 4107 儲存的是 Peterborough 實際收到的指令，女王在開頭和結尾都簽了名。標題是明寫的：Instructions for Our Right Trusty and Right Welbeloved Cousin and Councillor Charles Earl of Peterborow and Monmouth. Given at Our Court at St James’s the Two and Twentieth day of February 1711/2 in the Tenth Year of Our Reign.日期用的是舊曆，所以年份是1712年，而 DECODE 的年份範圍1711–1712指的就是這一封信。
書記把正文用明文寫出，把要緊的詞換成數字，用點隔開：We taking into Our Serious Consideration the great 2011.381. that are 966.298.534.76.1387.650.1108.389. Our good 435.823.755. the 1584.705.94.2211. of 2089.總共有61段，每段1到18個碼組，合計414個碼組，其中242個各不相同，範圍從76到2269。書記把 8 寫成帶圈的 ơ。f. 184v 裝訂縫處有兩個碼組丟了最後一位數字。除了下面的截圖，這裡不轉載 British Library 的影象。登入 DECODE 後可以檢視。
02 刊印文字與匹配
Parke 於1798年根據國務大臣官署的抄本刊印了 Bolingbroke 的檔案。在 St John 致女王的一封信的註釋中，他加了一句“Lord Peterborough’s instructions was as follow”，後面是全文，標題相同，日期相同，結尾同樣是 A. R.手稿中的明寫段落與印本逐字一致，而每段程式碼所在的位置，印本上都有一個短語：
| 程式碼段 | 程式碼 | 刊印文字 |
|---|---|---|
| 1 | 2011.381 | endeavours |
| 4–5 | 1584.705.94.2211 · 2089 | Electoral Prince · Saxony |
| 9 | 724.1604.678.1219.563.393.1893 | dishonour the Protestant interest |
| 17 | 839.534.678.523.412.303.1076.833.179 | you to the said Prince whom |
| 18 | 609.1415.705.564.1369 | his arrival at Rome |
| 43 | 385.97.894.1098 | himself |
| 44 | 422.474.373.900.609.507.1373 | abjuring his religion |
| 50–51 | 1799.900.894 · 465.355.385.466.615.755 | rescuing him · hands he is in |
| 55 | 886.354.839.1053.534.523.308.678.1285.500.1369.738 | given you leave to see the city of Rome |
| 60 | 720.425.295.335.534.2101 | come back to Turin |
全部61段的對齊見 alignment.tsv。重複出現的碼組證實了這一點：無論出現在哪裡，它們的含義都相同。534 在全部八處都是 to，而 678 the、839 you、894 him、466 he、609 his、981 your、1068 our、783 on 和 820 this 各自在三到七處保持不變。1373 在全部三處都是 religion，1219.563 兩次都是 Protestant。同一個音節 422 既是 abandon 的開頭，也是 abjuring 的開頭。在找到印本之前，其中四個值（894 him、466 he、894.1098 himself、981 your）已經根據周圍的明寫詞猜了出來。
這套程式碼在文字中大量填充虛碼。232個印刷詞對應414個碼組，一個詞可以佔四五個碼組：his 有一次寫作 328.333.388.467，him 寫作 326.332.349.467.2269。有些詞不止一個碼組（Prince 是 1076 或 2211；Rome 是 1369 或 519.488）。數字不按字母順序排列（466 he、609 his、894 him、981 your），所以它不是 SP 106/7 中儲存的那些印製好的一部本程式碼之一。有兩個單獨的碼組在印本中沒有對應的詞：church of Rome and 之後的 91，以及 affairs 261 bring him 中的 261。它們要麼是虛碼，要麼是底稿與謄清本之間的細微差異。
03 指令內容
下面的文字依據 Parke 的印本，拼寫已現代化。粗體的詞在手稿中是用程式碼寫的。
We taking into our serious consideration the great endeavours that are used to pervert our good cousin, the Electoral Prince of Saxony, to the superstitious worship of the church of Rome, and the infinite prejudice and dishonour the Protestant interest would suffer if so considerable a Prince, in whose country the reformation first began, should abandon the principles of our most holy religion, think it a duty incumbent on us to prevent, as far as in us lies, so fatal a blow. For that end, we have taken the resolution of sending you to the said Prince, whom you are to join, if possible, before his arrival at Rome, yet in such a manner that your falling-in with him may appear merely accidental: but whether you meet him on the road, or find him at Rome, you shall take a proper opportunity to deliver our letter to him, accompanying it with expressions of our friendship and real concern for his prosperity. You shall endeavour to insinuate yourself into his good opinion, and, as occasion offers, urge the strongest arguments you can for keeping him steady to the Protestant religion. If you find your representations make any impression upon his mind, you shall then open to him the subject of your commission, and declare that we have dispatched you to him on purpose to let him know that we have still the same earnest desire of seeing him which we have so often expressed; and that if he persists in those good resolutions he formerly had, to adhere firmly to the religion in which he was educated, he may depend upon a friendly and honourable reception in our Court, in case his inclination or the situation of his affairs bring him this way. If, upon discourse with him, you shall discover that he apprehends himself under a necessity of abjuring his religion, to avoid the dangers and difficulties he will otherwise be exposed to, and that he has an inclination to make his escape, you may concert with him the proper measures for rescuing him out of the hands he is in, and bringing him safe to our dominions, or those of any other Protestant Prince or State.
If you should happen to be arrived at Turin when these our instructions are delivered to you, you shall acquaint the Duke of Savoy that, in compliance with your request, we have given you leave to see the city of Rome; for you are by all means to prevent any suspicion of the true intent of your going thither.
The nature of this service in which we now employ you is such, that we can neither enjoin you to correspond with either of our Secretaries of State, nor limit the time of your return; we therefore leave it entirely to your discretion and prudence to come back to Turin when you shall judge your attendance on the Prince of no further use.
這位世子是 Frederick Augustus，強力王奧古斯特之子，後來的波蘭國王奧古斯特三世。Parke 的註釋解釋說，由於預期要迎娶一位天主教的女大公，世子“was about to set off for Rome, to abjure the Protestant religion”。書記把凡是點出世子、宗教、使命及其掩護說法的內容都寫成了程式碼。客套話和有關行事的指示則保留明寫。
04 仍不確定的部分
- 程式碼表。只確定了約二十個值。DECODE 上沒有一份金鑰能對上：SP 106 第6–8盒的全部金鑰，以及每一份轉錄過的、年代在1690–1730年的英國、TNA 或 Bodleian 金鑰，都用 894 him、466 he、1098 self 和 981 your 檢驗過。BL Add MS 61575 ff. 62–65 中的名單屬於馬爾伯勒，不是這套程式碼。
- 碼組 91 和 261，它們在印本中沒有對應；以及裝訂縫處兩個碼組的末位數字（52?、33?）。
- 不能排除在程式碼段內部，Parke 所據的官署底稿與簽署的原件之間存在措辭上的細微差異。各段的長度沒有顯示出任何差異。
