Terminal Command (bug?)

[Eddie W. Shore]

Used: Emulator - Firmware 14596

Changing the contents of Twitter lines is fine. For instance, this code changes the 1st line of the Terminal to "{5,#0000FFh}":

Code:

EXPORT test2()
BEGIN
PRINT();
A:=1;
PRINT(A);
Terminal(1):={5,#0000FFh};
END;

This code, which is attempting to turn the first line blue, crashes the emulator:

Code:

EXPORT test2()
BEGIN
PRINT();
A:=1;
PRINT(A);
Terminal(−1):={5,#0000FFh};
END;

Also, I assume object is what I want printed. I don't know what to use for flags.
