Even if NaaLaa is meant for games, there may be circumstances where you need to output or input some values.
procedure write [expr[, expr ...]]
procedure wln [expr[, expr ...]]
function rln([max_chars])
function rln#([max_chars])
function rln$([max_chars]
procedure set caret x, y
procedure set justification left/right/center
procedure center [expr[, expr ...]]
procedure set decimals decimal_digits
procedure set decimals integer_digits, decimal_digits
function inkey(clear_buffer)
function chr$(ascii_value)
function asc(a$)
Write a number of arbitrary expressions to current image.
Write a number of arbitrary expressions to current image and add a line break.
Return an integer value from user (keyboard). If max_chars is submitted, the user can enter a maximum of max_chars characters.
Return a floting point value from user (keyboard). If max_chars is submitted, the user can enter a maximum of max_chars characters.
Return a text string from user (keyboard). If max_chars is submitted, the user can enter a maximum of max_chars characters.
Set top left position (pixels) for text output/input to x, y.
Set justification of text output to left, right or center.
Write a number of arbitrary expressions centered and add a line break. Setting justification to center and using wln gives the same result.
Set number of decimal digits for text output to decimal_digits.
Set minimum number of integer digits for text output to integer_digits and the number of decimal digits to decimal_digits.
Return ASCII value of the last key that was pressed. If clear_buffer is set to true, the buffer of pressed keys will be cleared, else you can keep calling inkey until it returns 0.
Return a string containing the character represented by ascii_value.
Return ASCII value of the first character in a.
