PCB Editor SKILL Database IDs

Each element in the PCB Editor database has a unique database identifier that allows you to refer to that object and each element type has a specific set of member attributes.

Reading Data From a Text File Using SKILL

The SKILL programming language provides functions to allow you to easily read ASCII data from text files by opening a file, reading data from the file, and then closing the file when done.

Writing Data to a Text File Using SKILL

Controlling Program Flow with Multiway Branching in SKILL

The SKILL Programming language provides two multi-way branching functions to control the flow of your programs, the case() function and the cond() function. ​

Controlling Program Flow with Binary Branching

The SKILL Programming language provides three binary mechanisms to control the flow of your programs, the if() function, when() function and the unless() function.

Optional Arguments and Keyword Arguments in SKILL

When creating a user-defined procedure, SKILL provides a mechanism to allow optional arguments, keywork arguments, and an arbitrary number of arguments.
