| PRINT Statement Details |
|
| Syntax |
| PRINT [expressionlist][{,|;}] |
| |
| If expressionlist is omitted, a blank line is printed. If |
| expressionlist is included, the values of the expressions are printed |
| on the screen. The expressions in the list may be numeric or string |
| expressions. (String literals must be enclosed in quotation marks.) |
| |
| A printed number is always followed by a space. If the number is |
| positive, it is also preceded by a space; if the number is negative, |
| it is preceded by a minus sign (-). |
| |
| There are two formats that PRINT uses to display single- and |
| double-precision numbers: fixed point and floating point. If PRINT |
| can represent a single-precision number in the fixed-point format |
| with seven or fewer digits and no loss of accuracy, then it uses the |
| fixed-point format; otherwise, it uses the floating-point format. |
| For example, the number 1.1E-6 is output displayed as .0000011, but |
| the number 1.1E-7 is output as 1.1E-7. |
| |
| Similarly, if PRINT can represent a double-precision number in the |
| fixed-point format with 16 or fewer digits and no loss of accuracy, |
| then it uses the fixed-point format; otherwise, it uses the floating |
| point format. For example, the number 1.1D-15 is output as |
| .0000000000000011, but the number 1.1D-16 is output as 1.1D-16. |
| |
| The PRINT statement supports only elementary BASIC data types |
| (integers, long integers, single-precision real numbers, double- |
| precision real numbers, and strings). To print information in a |
| record, use the PRINT statement with individual record elements |
| as in the following fragment: |
| |
| TYPE MyType |
| Word AS STRING * 20 |
| Count AS LONG |
| END TYPE |
| DIM Myrec AS MyType |
| |
| PRINT Myrec.Word |
| |
| Print Positions |
| |
| The position of each printed item is determined by the punctuation |
| used to separate the items in the list. BASIC divides the line into |
| print zones of 14 spaces each. In the expression list, a comma makes |
| the next value print at the start of the next zone. A semicolon makes |
| the next value print immediately after the last value. Typing one |
| or more spaces or tabs between expressions has the same effect as |
| typing a semicolon. |
| |
| If a comma or a semicolon terminates the list of expressions, the |
| next PRINT statement prints on the same line, after spacing |
| accordingly. If the expression list ends without a comma or a semicolon, |
| a carriage-return and line-feed sequence is printed at the end of |
| the line. If the printed line is wider than the screen width, BASIC |
| goes to the next physical line and continues printing. |
