![]() The empty pair of quotes above should be used only with the := operator because if it were used with the = operator, it would store two literal quote-characters inside the variable. You may have guessed from the above that there are two methods to erase the contents of a variable (that is, to make it blank): MyVar = The latter method is preferred by many due to its greater clarity, and because it supports an expression syntax nearly identical to that in many other languages. The following examples are functionally identical to the previous ones: MyNumber := 123ĬopyOfVar := Var Unlike its counterpart in the previous section, percent signs are not used with the := operator. For example: MyNumber = 123ĬopyOfVar = %Var% With the = operator, percent signs are required to retrieve a variable's contents.īy contrast, the expression method uses the colon-equal operator (:=) to store numbers, quoted strings, and other types of expressions. The legacy method uses the equal sign operator (=) to assign unquoted literal strings or variables enclosed in percent signs. Storing values in variables: To store a string or number in a variable, there are two methods: legacy and expression. See Variables for general explanation and details about how variables work. When working with text, EXACTly equals (including case) requires the EXACT function.Variables and Expressions - Definition & Usage | AutoHotkey Variables and Expressions Table of Contents This one issue can be hard to find, but has a simple solution. So, remember to follow the Spreadsheet rules and you won’t run into this issue in your custom work that you are doing with your Tiller sheet. You can see above that the EXACT function sees the difference in cell A9, and correctly gives a FALSE answer in C9 and C10. The example below is the same data as above in Column A, but we are using the EXACT function in this case: ![]() So, if you are working with text fields and want an EXACT test that IS case sensitive, you will need to use the function EXACT in your IF statement. The text fields are equal since we are dealing with a case-insensitive match with an equals sign. So in our example above, it is correct per the spreadsheet rules. What happens in the background, is the text cells are shifted to lowercase before the test. For cells that are text values, when you use the equals sign (=) in an IF statement, the equals sign is CASE INSENSITIVE. Now we get back to the Spreadsheet rules. Cell A9 has a capital I in the “TIller Money” group name. Cell A9, looking closely at it is in fact slightly different – just a few pixels to your eye, but not EXACTly the same. They are all equal.īut if you look really close, you will see the problem. And as you can see above all the Group tests return TRUE. If it is equal, then we return TRUE, if it is not equal we return FALSE. ![]() See if you can see what the issue might be (the text of the functions are in column B and the actual functions are executed in column C):Īs you can see above, all we are trying to do is compare the previous group cell with the current group cell. We had some logic and functions that looked like this below. And so, when does equal not really mean exactly equal in a spreadsheet? In this case, it was a complex spreadsheet (with Java code behind it), but the issue was simple and small, hard to see, took time to find, but was a reminder to follow the rules.
