PT=

Format: PT="data"

Supported by: Floating Point BASIC 2.2

Similar commands: -

The PT= statment is used in conjunction with the SHOW statement to display patterns on the video screen. BASIC expects to find a series of up to 32 hexadecimal digits enclodes within mandatory quotes. Digits should be arranged as full bytes. If non hex characters are used an error will be generated. The last PT= statement executed remains valid until another one is defined.

Examples:

 
10 CLS 
20 PT="FF818181FF"
30 SHOW (0, 0): WAIT (100)

Will show a box in the upper left hand corner.

 
10 CLS
20 PT= "FFFFFFFF"
40 SHOW (0, 0, 8, 32)

Will fill the whole screen to white.

 
10 CLS
20 PT= "3838FFFFFFFF6666"
30 FOR A=0 to 56
40 SHOW (A, 120)
50 WAIT (10)
60 SHOW (A,120)
70 NEXT 

Will drive a little car across the bottom of the screen
