Conventions Used in this Handbook

The following notation conventions are used in this Handbook:

KEYWORDS

Capital letters indicate NS Basic/App Studio keywords and other text that must be typed exactly as shown. For the purposes of this manual, uppercase text indicates a required part of the Statement syntax. NS Basic/App Studio is case-insensitive: keywords are accepted with either uppercase letters, lowercase letters, or any mixture of the two. A keyword such as PRINT may be entered into your programs as print, Print, or PRINT.

placeholders

Italic text indicates a placeholder for types of information that you must supply. In the following Statement, expression is italicized to show that the EXECUTE statement requires an expression:
EXECUTE expression

Example

This Monaco typeface indicates example program code and information that is printed on your NS Basic/App Studio screen. The following example shows a line from an NS Basic/App Studio program: PRINT "Hello World!" [Optional] Brackets indicate that the enclosed items are optional. In the following example, brackets are used to show that entering a second item to display on the screen is optional for the PRINT statement: PRINT expression1 [ ,expression2 ] Both of these PRINT statements are legal, since PRINT accepts up to 20 expressions: PRINT "Hello" PRINT "Hello","World" | The vertical bar indicates that the items are mutually exclusive. In the following example the bar indicates that the LEN function can either be used with a string or a variable name: LEN(string | variable)
