For quite long time we were missing the ability to declare arrays in the SCL editor. Although arrays are not widely used in Process...

There is something interesting that I have not mentioned before. It was introduced along with the Time critical scripts but can be used...

VARIANT is yet another data type that you can use in your functions / function blocks. Usually it comes in handy when defining the...

When working with strings, often there is a need of doing string processing. e.g. searching, replacing, extracting substrings. SCL offers...

These are special symbols, often having specific syntax, used in programming and text formats to represent characters that are difficult...

Some time ago a customer asked if we can display numbers in hexadecimal format. It was a question related to the simulation panel in...

Snippets are standard across programming languages. They are small portions of text that can easily be inserted while you type. The text...

If you recall, some time ago I showcased the usage of a custom motion profile on joints. It was just a function that calculates the...

Expressions are everywhere - we use them when expressing conditions, formulas, logic. But how do we position them in the code? We...

We all know that values are assigned to variables using the assign (:=) operator. But do you know that the assign operator may be used...

You already know how to add new functions, function blocks and data types using the script. It is easy - just import the related text...

Introspection means extracting semantic (meaningful) information from the code. For example: getting variable names, type names, default...

When you need to compare two integers for equality you use the equality (=) operator in SCL. This is so intuitive that it hardly needs to...
