Comparison operators
=, is
Results in true if the expression to its left and the expression to its right have the same values. The expressions can be arithmetic, text, or logical.
N = 0
word 1 of card field 1 = 10
the name of this card is "Index"
<>, ≠, is not
Results in true if the expression to its left and the expression to its right have different values. The expressions can be arithmetic, text, or logical.
the number of this card <> 1
the number of this card ≠ 1
the name of this card is not "Index"
Note: To get the character ≠ , hold down Option and press = .
<
Results in true if the expression to its left has a value less than the one to its right. The expressions can be both arithmetic or both text.
the number of this card < 10
the freesize of this stack < 5120
>
Results in true if the expression to its left has a value greater than the one to its right. The expressions can be both arithmetic or both text.
23 > 13
the version > 1.2.5
(the freesize of this stack) > 10240
<=, ≤
Results in true if the expression to its left has a value less than or equal to the one to its right. The expressions can be both arithmetic or both text.
the number of this card ≤ 10
the freesize of this stack <= 5120
Note: To get the character ≤ , hold down Option and press < .
>=, ≥
Results in true if the expression to its left has a value greater than or equal to the one to its right. The expressions can be both arithmetic or both text.
23 >= 13
the version ≥ 1.2.5
(the freesize of this stack) ≥ 10240
Note: To get the character ≥ , hold down Option and press > .
Contains
Results in true if the text string yielded by the expression on its right is found in the text string yielded by the expression on its left (the converse of the operator is in ).
"hello world" contains "lo wo"
the name of this card contains "operator"
is in
Results in true if the text string yielded by the expression on its left is found in the text string yielded by the expression on its right (the converse of the operator contains ).
"lo wo" is in "hello world"
"operator" is in the name of this card
is not in
Results in true if the text string yielded by the expression on its left is not found in the text string yielded by the expression on its right (the opposite of the operator is in ).
"Apple" is not in "oranges"
"operator" is not in the name of this card
is within
Results in true if the point yielded by the expression on its left is contained within the rectangle yielded by the expression on its right.
"20,20" is within "0,0,40,40"
the mouseLoc is within the rect of ¬
card button 1
is not within
Results in true if the point yielded by the expression on its left is not contained within the rectangle yielded by the expression on its right.
"20,20" is not within "0,0,15,15"
the mouseLoc is not within the rect of ¬
card button 1
