Description
The ? command outputs a carriage return, then a line feed, then evaluates each expression in turn and displays the result. The ?? command evaluates the expression and displays the results on the same line, no carriage return/line feed sequence is output. If more than one expression is specified and SET SPACE is ON, a single space is output between each expression. If SET SPACE is OFF, the expressions are output with no space in between.
| Clause | Description |
|---|---|
| AT <expN> | You may optionally specify the column at which the expression will be output with the AT <expN> clause. |
| PICTURE <expC1> | The PICTURE clause supports all picture template symbols listed in the @...SAY command. |
| FUNCTION <expC2> | The FUNCTION qualifier allows picture functions to be specified. Normally this can be done with the PICTURE qualifier by preceding the picture with '@'. If the FUNCTION qualifier is used the '@' is not needed. |
| STYLE <expC3> | The STYLE qualifier has been added for compatibility with other Xbase languages. |
In Recital Mirage, the following style qualifiers are supported in <expC3>:
| <expC3> | Style |
|---|---|
| B | Bold |
| I | Italic |
| U | Underline |
Example
? "price" at 01 picture "@!",1234.56 picture "$99,999.99" PRICE $1,234.56
