	The FORM statement provides you with several conversion specification options, but the two that you will probably use most frequently are C and N. C stands for character, and it signals that the system is to print a character string. N stands for numeric, and it signals that the system is to print a numeric ~~number~~. The second numeric parameter in the specification indicates the length of the field where it will print.

Mikhail.zheleznov: numeric strings which contain more than ten whole number digits are printed in exponential form. (Used to be 6 digits I guess)

	The information in the right corner of your status line allows you to keep track of the cursor’s current screen position. The number on the left side of the colon shows the cursor’s row number (since the cursor does not scroll, this number will almost always be 24 when you are writing a program), and the number to the right of the colon shows the column number.

	You have already used the PRINT statement for unformatted printing. When an unformatted PRINT statement is executed, numeric strings which contain more than ~~six~~ whole number digits are printed in exponential form, and numeric strings which contain more than six decimal digits are rounded.

	The first number (1.~~2345678e~~+~~008~~) is printed in exponential form, and the second (0.~~123456~~) is rounded to six digits.		The first number (1.2345678901e+10) is printed in exponential form, and the second (0.123457) is rounded to six digits.

	Formatted PRINT statements allow you to choose the number of digits which will appear before exponentiation or rounding occurs. Formatted printing is usually used in reports, where information must fit into predetermined slots. This is described later in the chapter.

	The dollar signs are special characters that operate both as insertion characters and as digit identifiers. As insertion characters, they tell the system to insert one dollar sign just before the first digit in the number. As digit identifiers, they tell the system to put a digit from the number to be printed in their places. If there are more digit identifiers than there are digits (as in the following case, where there are six dollar signs and only four digits), Business Rules! prints a space instead of the extras.

	The comma and the period which appear within the parentheses are insertion characters. Most characters on your keyboard (except Z, #, B, CR, DR, and DB) can be used as insertion characters, but these are two of the most common. (Other common characters include the - and + symbols.) The pound signs (##) appearing after the period are more digit identifiers. Number signs tell the system to print a digit at that spot even if it must be a zero.
