The '''POS''' function returns the current print cursor text column position.
|
|
|
|
|
|
{{PageSyntax}}
|
|
:: column% = POS(0)
|
|
|
|
|
|
* The value in parenthesis is normally 0, but any numerical value or variable could be used for compatibility with Basic.
|
|
* When a semicolon ends the previous PRINT statement the cursor column position will be after the last character printed.
|
|
* If [[TAB]] or a comma is used the column position will be immediately after the tabbed position normally 9 spaces after text
|
|
* If a [[PRINT]] statement does not use a semicolon or comma at the end, the return value will be 1 on the next row.
|
|
* Column position returned can be saved to return to a previous print position later using [[LOCATE]].
