Migrating from EZ-Script to JavaScript
Case Sensitive
JavaScript, much like many programming languages, is case sensitive for variabes and functions. That means a variable named "MyVariable" is different than "myVariable". This applies to all variables, commands and functions.
Example
Here is an example program that demonstrates how the different case of a variable makes two different variables.
Code:
var MyVariable = "ONE";
var myVariable = "TWO";
print(MyVariable);
print(myVariable);
The output of that example will demonstrate how ONE and TWO are both printed. This is because the case sensitive variable name is taken into consideration for that variable.

Edit.... I think I had a similar question last week about using my old EZ scripts and did you point out some tutorial Link? I seem to have forgot where.
The windows Copy and Paste command will copy the text. There is no way to "convert code" when pasting. It will merely paste what is copied. Once you paste the EZ-Script into the JavaScript window, you can edit the code to make it JavaScript syntax.
