About twenty years ago, I came into contact with a software which can draw (e.g. a line) by typing on it (e.g. typing some code, then push "ENTER" (I am not sure about this part), a line will appear on the screen). I think there was no way to choose the color of the drawn line.
Now I want to look at this software again, but I did not remember the software name. Do anyone on this site have any idea what this software is?
To rephrase, I am asking for a software that draw (e.g. a possibly one-colored line) by typing on it (e.g. typing some code, then push "ENTER" (I am not sure about this part), a line will appear on the screen).
PS. Please inform me if the you think that this is not an appropriate question to ask here.
