Char$() function

[Brian Walsh]

I'm completely new to this, so sorry in advance for the dumb nature of the question.

Details of the Char$() function are missing from the help file, so I assumed that the decimal value of the required ASCII character goes between the brackets.

I have a working program which has a variable: string = "hello world ".

When I go into the properties of the string manipulation box and edit it to: string = "hello world " + Char$(13) + Char$(10) I get a syntax error.

Any help greatly appreciated.

Brian.

I believe the Char$() function is used to produce a numeric value from a string variable.
E.g
String = "hello world"
Num = Char$(string, 2)

This would assign variable Num (numeric variable) with the value of 108 since ASCII Dec value of l is 108.

I know the LCD has a function to display ASCII characters.

Thanks for that. It appears that the char$() function is not what I'm after. I'll post another question.

Hello Brian

You should be able to do this to acheive what you are trying to do.

Variables
string1[20]
string2[2]

Calculation
string2[0] = 13
string2[1] = 10

String Manipulation
string1 = "Hello World" + string2

Hi. I believe (topically enough) that Char$(string, index) is what you want. This pulls the character out and returns it as its ASCII value.

If you want to print this number to some output (convert it to text) use the ToString$() function:

Code: Select all

value = Char$(buffer, 0)
text = ToString$(value)

Cheers,

Hi guys

Just a quick question is it possible to say in a decision for example bigger than 10 but smaller than 100

Hi Brian,

Code: Select all

(var > 10) && (var < 100)
