Functions
Available Armstrong functions.
Define
Macro that sets a memory address to the
given values before the program is executed.
Syntax
define 〈 Ａｄｄｒｅｓｓ 〉 〈 Ｖａｌｕｅ 〉
Example
define 0xff2 33
Change
Assigns the given address the supplied value.
Syntax
change 〈 Ａｄｄｒｅｓｓ 〉 = 〈 Ｖａｌｕｅ 〉
Example
change $cursorChar = 8
Add / Subtract / Multiply / Divide
Combines the two given values depending on the
operator and saves the result at the given address.
Syntax
〈 Ｏｐｅｒａｔｏｒ 〉 〈 Ｖａｌｕｅ Ａ 〉 , 〈 Ｖａｌｕｅ Ｂ 〉 -> 〈 Ａｄｄｒｅｓｓ 〉
Example
add $A , $B -> $C // A + B
mul $A , $B -> $C // A * B
sub $A , $B -> $C // A - B
div $A , $B -> $C // A / B
Goto
Jumps to the given address or label.
Syntax
goto 〈 Ａｄｄｒｅｓｓ 〉
Example
goto #mainLoop
Goto If
Jumps to the given address or label if the
comparison of the two values return true.
Syntax
gotoif 〈 Ｖａｌｕｅ Ａ 〉 〈 Ｃｏｍｐａｒａｔｏｒ 〉 〈 Ｖａｌｕｅ Ｂ 〉 , 〈 Ａｄｄｒｅｓｓ 〉
Example
gotoif $pixPos < 4095 , #colorScreen
gotoif $pixPos == 4095 , #colorScreen
If
Enters the logic block if the comparison
of the two given values returns true.
Syntax
if 〈 Ｖａｌｕｅ Ａ 〉 〈 Ｃｏｍｐａｒａｔｏｒ 〉 〈 Ｖａｌｕｅ Ｂ 〉 :
〈 Ｌｏｇｉｃ Ｂｌｏｃｋ 〉
endif
Example
if $ballPosY > 62 :
change $ballVelY = 1
endif
