Large+fonts+and+the+text+cursor

//by Richard Russell, December 2007//

BBC BASIC for Windows normally displays a text cursor (//caret//), by default consisting of a flashing underscore, the main purpose of which is to indicate to the user where a character typed at the keyboard will appear (for example when entering information in response to an [|INPUT] statement). The cursor can be disabled using the [|OFF] statement, and it is automatically hidden in the [|VDU 5] (text at graphics cursor) mode.

However, a text cursor is //not// displayed if you select a font size with a character height of more than about 32 pixels (corresponding to about 24 points at 96 DPI). If you need to display a cursor with large fonts you can still do so by selecting a full-height 'block' cursor as follows:

code format="bb4w" *FONT Courier New,28 VDU 23,0,10;0;0;0; code Alternatively you can select a 'vertical line' cursor (which is more suitable for a proportional-spaced font):

code format="bb4w" *FONT Arial,28 VDU 23,0,18,2,0;0;0;23,0,10;0;0;0; code Note: To permit satisfactory input editing when using a proportional-spaced font you should use the **FNpsinput** routine (which can be found [|here]) rather than the **INPUT** statement.
