Comment

You can use the NO command or apostrophe (') to add comments to the program.

Executing Programs - Multitasking

Up to 8 independent programs (threads) can run simultaneously, and instructions for starting and stopping threads are introduced.

debugger

Provide commands and operands that help debug applications, such as trace commands, error code commands, stop code commands, etc.

Program flow command

Including event triggers and conditional jumps, the program flow can be changed based on the occurrence of events.

Mathematics and Function Expressions

Provides a variety of mathematical operators and functions that can be used for data manipulation.

variable

Provides 510 variables that can be used to store mutable parameters, and introduces the definition and assignment of programmable variables.

array

Used for storing and collecting numerical data, this article introduces the definition, assignment, upload and download of arrays, as well as automatic data capture functions.

Data input (numerical and string)

The IN command can be used to prompt the user to enter numerical or string data, introducing the operator data input mode and the use of communication interruption.

Data output (numerical and string)

MG commands can be used to output numerical and string data, introducing message sending, port specification, and formatting.

Hardware I/O
