DATA • HP BASIC does not execute DATA statements. Instead, control is passed to the next executable statement. • A program can have more than one DATA statement. HP BASIC assembles data from all DATA statements in a single program unit into a lexically ordered single data block. • HP BASIC ignores leading and trailing blanks and tabs unless they are in a string literal. • Commas are the only valid data delimiters. You must use a quoted string literal if a comma is to be part of a string. • HP BASIC ignores DATA statements without an accompanying READ statement. • HP BASIC signals the error ‘‘Data format error’’ if the DATA item does not match the data type of the variable specified in the READ statement or if a data element that is to be read into an integer variable ends with a percent sign ( % ). If a string data element ends with a dollar sign ( $ ), HP BASIC treats the dollar sign as part of the string. Example 10 DECLARE INTEGER A,B,C READ A,B,C DATA 1,2,3 PRINT A + B + C Output 6 3–34 Statements and Functions
