BKG

Format: BKG X

Supported by: Telmac SBASIC v 24.3

Similar commands:
COMX BASIC V1.00: SCREEN
Floating Point BASIC 2.2: COLOR
Pecom 32 BASIC, Pecom 64 BASIC 1.0 and 4.0: SCR

The BKG command is in the format, BKG X, where X is a numeric expression (varying from background 0 to 7 inclusively) which determines the colour of the background. The different background colours corresponding to different values of X are given in Table 1.

Now, try the command

BKG (1)

followed by pressing CR, and note that the background colour changes from black to green. Replace the "1" by numbers from 0 to 7 inclusive, and compare the background colour observed with Table 1. Note that BKG (0) corresponds to the default background colour. Note also that if either the characters have the same colour as the background, the characters would not be visible.
