Question

how would i tell tracy to move forward 100 pixels?
forward 100
move 100
forward (100)
tracy, move forward 100 pixels

Explanation:

In programming (Computer Science sub - field), when using a simple turtle - like graphics or movement commands (assuming Tracy is a simple graphical object with a defined set of commands), the common syntax for moving forward a certain number of pixels is in the form of a function call. The forward(100) format is typical as it follows the function - argument syntax (where forward is the function name and 100 is the argument representing the number of pixels). The forward 100 and move 100 lack the proper syntactic structure (no parentheses for arguments in a function - like call in many programming - related movement command systems), and Tracy, move forward 100 pixels is more of a natural - language instruction rather than a programming - syntax command.

Answer:

forward (100)
