so i made this BASIC text editor and it is so simple that alls you do is type the file name and type only one line of text and you click enter it says thank you and press enter and it says what you wrote.
well it says runtime error (file not exist) at line 18
so i'm wondering why it won't work. any help is great.

nameoffile$ = you haven't assigned a value to this variable

filename$ = "C:\AdamDBP FILE\Text editor v1\" + nameoffile$ + ".dat"

I think what Phealax is telling you is that you must use string concatenation to create a complete string for the variable "filename$". Hense, the use of the "+" sign.

Also, I would recommend checking to see if the user actually entered something at the input other than just pressing the enter key. This way your variable, "nameoffile$" isn't null (empty). You could either make it a default string referencing a default file and path, or just have the user re-enter something until "nameoffile$" is not null.

The sync commands are used to set a constant frame rate used in your program no matter what the computer specs are running it. This is sometimes refered to as the screen refresh rate.

In a game situation there is many different things moving on the screen. Usually, you would have all the actions determined inside of a loop of some sort. During each pass of the loop something is calculated and then repositioned. At the end of each pass of the loop, the sync command updates (redraws) the screen.

Here is a generic example of usage:



Using a sync rate of zero will cause the program to refresh as fast as the system will allow.

There is a speed break point you can reach. This means if the frame rate is set to a speed which the program can not handle then you wont get the actual frame rate specified by the sync rate command. This can be due to limitations of the langauge and poor programming practices.
