Description

W[RITE]

W[RITE]: (variable|*variable|formatting)

Arguments:

Must be one of the following:

  • variable
  • string litteral
  • format command
  • *variable

When the arguments are variables or string litterals, they get to be written to the current output device, as defined by the variable $IO, or set by the USE Command.

Formatting commands control how the cursor is going to be manipulated before and after writing the text.

When the argument is a numerical expression preceeded by the * symbol, then the expression is used as an ASCII value and the WRITE command prints the character corresponding to that ASCII value.

Examples

WRITE "Hello ",YOURNAME,!

WRITE \*65

This prints the letter A which is the character corresponding to the ASCII value 65.
