Colours

Overview

JET 3270 operates in either base colour mode or extended colour mode.

Base colour mode is the initial state. In this mode the colour of text is determined by the protect and intensify bits of the field attribute.

JET 3270 switches to extended colour mode if it recieves the foreground colour or background colour attribute types. In this mode the foreground and background colour of text is determined by its character and extended field attributes. If both the character and extended field attributes specify the default foreground colour then the colour is determined by the intensify bit of the field attribute. If both specify the default background colour the background colour preference is used. Nine preferences in the Extended Colours group configure these colours.

JET 3270 returns to base colour mode if it receives an Erase/Write or Erase/Write Alternate command with the reset bit of the WCC set to one or the user presses the Clear key.
