I think I may have found a bug with the TICKER command in MPAGD 0.7.9.
In my game I am using variable H to hold the number of a message
so TICKER 15 H should display message H in a ticker 15 characters wide. However it doesn't, and in the build window there is message: "invalid argument for TICKER on line 3828"
strangely, if I use TICKER H H - it works (it will show message H in a ticker H characters wide)
As a workaround if I have a variable T, that holds the number of characters I want the Ticker to be wide, and use TICKER T H - it all works fine. However, variables are at a premium for me at the moment and I'd really prefer not to use one just to hold a number (T) that wont ever change.
