::: Cout cursor Macro. Author: T3RRY ::: Filename: Cout.bat::: OS requirement: Windows 10::: Purpose: Facilitate advanced console display output with the easy use of Virtual terminal codes::: Uses a macro function to effect display without users needing to memorise or learn specific::: virtual terminal sequences.::: Enables output of text in 255 bit color at absolute or relative Y;X positions.::: Allows cursor to be hidden or shown during and after text output.
