Robot style EOF?

[Metalgod4eva]

does anyone have some form of proof of this no such thing as a data stream on the robot, because the pwm passes chars to the engine and one would think that in theory that alone is a data stream and without EOF issues in ending the stream would have an issue.
MPLAB: The MPLAB® C18 compiler is a full-featured ANSI compliant C compiler for the PIC18 family of PICmicro® 8-bit MCUs. MPLAB C18 is a 32-bit Windows® console application as well as a fully integrated component of Microchip’s MPLAB Integrated Development
Supports ANSI so then it must use things like EOF, enum, etc all of which people have said is not complient with the robot.
