| READ variablelist |
| |
| A variablelist is a series of valid BASIC variables separated by commas. |
| |
| READ statements are always used with DATA statements. READ assigns DATA |
| values to variables on a one-to-one basis. These variables may be numeric |
| or string. Attempting to read a string value into a numeric variable |
| produces a run-time syntax error. Reading a numeric value into a string |
| variable does not produce an error, but stores the value as a string of |
| numerals. |
| |
| Values read into integer variables are rounded before the value is assigned |
| to the variable. Reading a numeric value too large for a variable produces |
| a run-time error. |
| |
| String values read into fixed-length string variables are truncated if the |
| string is too long. String values shorter than the string-variable length |
| are left-justified and padded with blanks. |
| |
| Only individual elements of a record variable may appear in a READ statement. |
| |
| A single READ statement may use one or more DATA statements (they will be |
| used in order), or several READ statements may use the same DATA statement. |
| If there are more variables in variablelist than there are values in the |
| DATA statement or statements, an error message is printed that reads |
| "Out of DATA." If there are fewer variables than the number of elements |
| in the DATA statement or statements, subsequent READ statements begin |
| reading data at the first unread element. If there are no subsequent |
| READ statements, the extra items are ignored. |
| |
| Use the RESTORE statement to reread DATA statements. |
