| INPUT Statement Details |
|
| Syntax |
| INPUT[;]["promptstring"{;|,}]variablelist |
| |
| Argument Description |
| ; A semicolon immediately after INPUT keeps the cursor |
| on the same line after the user presses ENTER. |
| promptstring A string constant printed before the prompt |
| character. |
| ; Prints a question mark at the end of the |
| promptstring. |
| , Prints the promptstring without a question mark. |
| variablelist A list of variables, separated by commas, to accept |
| the input values. See the discussion below. |
| |
| The INPUT statement causes the program to pause and wait for data. |
| You can then enter the required data at the keyboard. |
| |
| The data that you enter is assigned to the variables in variablelist. |
| The number of data items that you supply must be the same as the |
| number of variables in the list. The first character encountered after |
| a comma that is not a space, carriage return, or line feed is assumed |
| to be the start of a new item. |
| |
| The variable names in the list may be numeric- or string-variable |
| names (including subscripted variables), array elements, or elements |
| of records. The type of each data item that you input must agree with |
| the type of the variable. (Strings input to an INPUT statement |
| need not be surrounded by quotation marks.) If this first character |
| is a quotation mark ("), the string item will consist of all |
| characters read between the first quotation mark and the second. This |
| means a quoted string may not contain a quotation mark as a character. |
| If the first character of the string is not a quotation mark, the |
| string is an unquoted string and terminates on a comma, carriage |
| return, or line feed. |
| |
| Input stored in elements of a record must be input as single elements: |
| |
| TYPE Demograph |
| FullName AS STRING * 25 |
| Age AS INTEGER |
| END TYPE |
| |
| DIM Person AS Demograph |
| INPUT "Enter name and age: ";Person.FullName,Person.Age |
| |
| Responding to an INPUT statement with too many or too few items, |
| or with the wrong type of value (for example, numeric instead of |
| string), produces an error message which reads "Redo from start." |
| |
| No assignment of input values is made until you give an acceptable |
| response. |
| |
| It is possible to edit a line of input before you press ENTER. The |
| following list describes the key combinations that allow you to |
| move the cursor, delete text, and insert text on the input line: |
| |
| Keys Action commands, INPUT statement |
