CLEO Sources

Hey!

I thought a thread where you can post some generic sources would be cool and useful.
So I start with a source to read a number out of a textfile.
Generaly it converts a string to an integer... You can modify this to get a StrToI function.

Notes: Create a file and write a number in ".." (Example: "123") it. The Source finds out the start (") and reads the number. if it founds " it returs the read numbers as an integer. If it founds an illegal character it should simply continue calculation.

Re: CLEO Sources

Good, but the code need to be optimized.

How 'bout making a routine that will read a word from the file (until it meets a space sign #32), and store this word to a string variable. Say, I have a file with

Hello, world!

inside. Then I run this routine and it will store Hello, to some variable. The routine could have an additional parameter to specify which word I need: first, second, third, etc. In my example, Hello, is the first word  and world! is the second. Also it could optionally skip everything except letters and numbers.

It will be useful to make a real routine StrToInt, that converts a string variable value to a number.
Then, to get a number from the file, I will run first routine with parameter 1, 2, etc and then the StrToInt.
