{{Parameters}}
|
|
* One of 3 mode keywords is mandatory when using this statement to deal with the text background.
|
|
**''_KEEPBACKGROUND'' (mode 1): Text background transparent. Only the text is displayed over anything behind it.

|
**''_ONLYBACKGROUND'' (mode 2): Text background only is displayed. Text is transparent to anything behind it.
|
|
**''_FILLBACKGROUND'' (mode 3): Text and background block anything behind them like a normal [[PRINT]]. '''Default setting.'''
