Using standard COBOL values

The first way, provided for compatibility reasons, uses up to sixteen values, numbered from 1 to 16. Values 1 to 8 are base colors, 9 to 16 are their brighter version. The file "iscobol.def" contains the color definitions. They are divided into groups, and can be combined:

ForegroundColor	78 black value 1. 78 blue value 2. 78 green value 3. 78 cyan value 4. 78 red value 5. 78 magenta value 6. 78 brown value 7. 78 white value 8. 78 dark-gray value 9. 78 bright-blue value 10. 78 bright-green value 11. 78 bright-cyan value 12. 78 bright-red value 13. 78 bright-magenta value 14. 78 yellow value 15. 78  bright-white value 16.
ForegroundBrightness	78 frgrnd-low value 2048. 78  frgrnd-high value 4096.
BackgroundColor	78 bckgrnd-black value 32. 78 bckgrnd-blue value 64. 78 bckgrnd-green value 96. 78 bckgrnd-cyan value 128. 78 bckgrnd-red value 160. 78 bckgrnd-magenta value 192. 78 bckgrnd-brown value 224. 78 bckgrnd-white value 256. 78 bckgrnd-dark-gray value 288. 78 bckgrnd-bright-blue value 320. 78 bckgrnd-bright-green value 352. 78 bckgrnd-bright-cyan value 384. 78 bckgrnd-bright-red value 416. 78 bckgrnd-bright-magenta value 448. 78 bckgrnd-yellow value 480. 78 bckgrnd-bright-white value 512.
BackgroundBrightness	78 bckgrnd-low value 65536. 78 bckgrnd-high value 131072.
GenericAttribute	78 color-reverse value 1024. 78 color-underline value 8192. 78 color-blink value 16384. 78 color-protected value 32768.

When an color value is used with a property that defines both the foreground color and the background colors, the value is computed as follows:

Zero   [ + ForegroundColor]   [ + ForegroundBrightness]   [ + BackgroundColor]   [ + BackgroundBrightness]   [ + GenericAttribute ] ...

When an color value is used with a property that defines either the foreground color or the background color, the value can be only 0 to 15 and the corresponding color is applied to foreground or background. The table below shows the possible values for BACKGROUND-COLOR and FOREGROUND-COLOR properties.

0 Black 1 Blue 2 Green 3 Cyan 4 Red 5 Magenta 6 Brown 7 White 8 Dark Gray 9 Bright Blue 10 Bright Green 11 Bright Cyan 12 Bright Red 13 Bright Magenta 14 Yellow 15 Bright White

Brightness can be also affected by the following clauses:

BACKGROUND-HIGH BACKGROUND-LOW BACKGROUND-STANDARD HIGHLIGHT LOWLIGHT STANDARD

When the REVERSE-VIDEO phrase is specified, background and foreground colors are swapped.

When the SAME phrase is specified, the whole screen item for which it is specified is displayed with the same colors and attributes of the screen position occupied by its first character.

Properties that define both the foreground color and the background color are:

•	Cell-Color

•	Cell-Current-Color

•	Cell-Entry-Color

•

•	Column-Color

•	Cursor-Color

•	Drag-Color

•	Heading-Color

•	Region-Color

•

•	Row-Color-Pattern

•	Row-Cursor-Color

Properties that define only the background color are:

•	Background-Color

•	Cell-Background-Color

•	Cell-Current-Background-Color

•	Cell-Entry-Background-Color

•	Column-Background-Color

•	Cursor-Background-Color

•	Decoration-Background

•	Drag-Background-Color

•	Heading-Background-Color

•	Row-Background-Color

•	Row-Background-Color-Pattern

•	Row-Cursor-Background-Color

Properties that define only the foreground color are:

•	Cell-Current-Foreground-Color

•	Cell-Entry-Foreground-Color

•	Cell-Foreground-Color

•

Colors

•	Column-Foreground-Color

•	Cursor-Foreground-Color

•	Divider-Color
