- The PSET statement has the syntax
PSET [X-coordinate (column), Y-coordinate (row), (Color of Pixel)]. - ATRAC3 should be installed into the system unit to open a .wav file.
Sound and Music
- The PLAY statement has the syntax
PLAY 'String', where the string represents a series of alphabets, numbers, and symbols that collectively produce a musical string in terms of octaves, notes, and duration. - In the SOUND command syntax, duration refers to the number of system clock ticks for which the sound plays.
