I am trying to build a program that allows me to input certain variables then save them as a text document onto my computer. How od I do this?

Use the following commands:
OPEN TO WRITE File Number, Filename <-- This command opens a file for writing. You can now write stuff in the file.

WRITE STRING File Number, String <-- Use that if you want to write text to your file. Keep in mind that each time you call this command the text will be printed on a new line.

WRITE WORD File Number, Integer Number <-- Use that if you want to write an integer number... Keep in mind that this number will appear in strange symbols if you open the file in notepad. Write string is your best bet if you want to be able to read your text document in notepad.

WRITE FLOAT File Number, float value <-- Use that if you want to write a float to a file. This will also appear in weird symbols, so Write String would be best if you want to be able to read your files in notepd.

CLOSE FILE File Number <---This command will close the file. The file is done when you call this command. You can no longer write to it.

Remembering that you can't open to write a file which already exists.



The above code snippet will help round that

If you want to append data to an existing file you must load the data into DBP, then delete the file, then write the whole file again including the bit you wish to append.

Hope that helps

Is there anything you haven't written a plug in for? Lol

Sure. I only have 800+ commands in 30 plug-ins so far, so there's tons of room for more

alright but how do I make it so that I can have someone input something and then save that to a file so that it can be viewed as a text document?

This is maybe a little simplistic for what you want, but it should point you in the right direction.

It really depends on how much data we're talking about? Here are some suggestions, however most of these have already been suggested. See how you get on trying them.

1) Keep the variables in an array and save that when the program exits.

2) Load the file into an array, add the new variables to the array and then resave the file (this is what I do, altho it would be impractical with hundreds of mb of Data)

3) Download and try IanM's plug in.

Here is an example that loads the file in and allows you to add more names and ages before exiting and saving.



Its maybe a bit clumsy, but it works and hopefully will help you in the right direction.

(Sorry for the Edit, that'll teach me for not testing the code properly)
