Standard sizes for NCR forms are half page (5.5″ x 8.5″), full page (8.5″ x 11″) and legal (8.5″ x 14″) although custom sizes can be ordered to meet your specific need. The design orientation can be either vertical or horizontal. The link below gives you access to design templates that can be used to lay out your form in the appropriate size and orientation.
There are many types of machines printers used to number Carbonless forms. One style is a letter press, another is a pneumatic numbering head which uses air pressure do drive a numbering head and crash imprint the number on the top sheet transferring the number to the other sheets. For example, if you were numbering a 2 part carbonless form you would have a black or red number on the top sheet and a crashed number on the second sheet. The image on the second sheet would appear black no matter what ink was on the top sheet as the carbonless paper transfers the image in black.

A sequence can be thought of as a list of elements with a particular order. Sequences are useful in a number of mathematical disciplines for studying functions, spaces, and other mathematical structures using the convergence properties of sequences. In particular, sequences are the basis for series, which are important in differential equations and analysis. Sequences are also of interest in their own right and can be studied as patterns or puzzles, such as in the study of prime numbers.
An alternative to writing the domain of a sequence in the subscript is to indicate the range of values that the index can take by listing its highest and lowest legal values. For example, the notation {\displaystyle (k^{2})_{k=1}^{10}} denotes the ten-term sequence of squares {\displaystyle (1,4,9,...,100)} . The limits {\displaystyle \infty } and {\displaystyle -\infty } are allowed, but they do not represent valid values for the index, only the supremum or infimum of such values, respectively. For example, the sequence {\displaystyle (a_{n})_{n=1}^{\infty }} is the same as the sequence {\displaystyle (a_{n})_{n\in \mathbb {N} }} , and does not contain an additional term "at infinity". The sequence {\displaystyle (a_{n})_{n=-\infty }^{\infty }} is a bi-infinite sequence, and can also be written as {\displaystyle (...,a_{-1},a_{0},a_{1},a_{2},...)} .
If you start to type in what appears to be a numbered list, Word formats your manually typed "numbers" to an automatic numbered list. The main benefit of this option is that you do not need to click any button to start numbering and you can choose your numbering style as well. For example, if you type "(a) some text" and press Enter, it starts numbering using the "(a)" format.
I have now permanently “baked” the Inline Counter system into my InDesign defaults. With no documents open, I made a “Counter” CharStyle and a “Zero Footnote” ParStyle, with those crucial zero-level type size attributes, and selected them in the Document Footnote Options. I also added a blank space as a prefix and a period and a blank space as a suffix. Then I made a keyboard shortcut (Ctrl-Alt-F) for the Footnote/Counter. So now Inline Counters can be inserted anywhere and anytime with close to zero efforts.

Select the Text Tool (T) and start dragging a text box that will wrap around the whole ticket including the crop marks. This is very important since the Data Merge will automatically calculate the duplication. Then open up the Text Frame Option (Command + B) and set the Inset spacing to 1p4 for the top and 1p8 for the left. Of course, you can place the text for the numbers anywhere you like. I set the numbers to a small text.
Apple has a formalized version number structure based around the NumVersion struct, which specifies a one- or two-digit major version, a one-digit minor version, a one-digit “bug” (i.e. revision) version, a stage indicator (drawn from the set development/prealpha, alpha, beta and final/release), and a one-byte (i.e. having values in the range 0–255) pre-release version, which is only used at stages prior to final. In writing these version numbers as strings, the convention is to omit any parts after the minor version whose value are zero (with “final” being considered the zero stage), thus writing 1.0.2 (rather than 1.0.2b12), 1.0.2 (rather than 1.0.2f0), and 1.1 (rather than 1.1.0f0).
