Hi Guys,

Is it possible to convert a character to its ASCII value using a batch file?

Here is a pure batch solution I developed with jeb's help: Re: new functions: :chr, :asc, :asciiMap It is a lot of code, but it performs fairly well and supports all characters except 0x00.

There is quick and dirty way to convert ascii codes between 32 and 126 into the character. For example, the code below will echo "A"


Finally, there is a nifty Command Line Calculator derived from AutoIT that supports a huge range of functions, including functions that will convert between ASCII codes and ASCII characters (both directions). http://www.brothersoft.com/command-line ... 53523.html
Again, this is slower than the pure batch functions because of the overhead of launching a rather large executable for each conversion. But it is very convenient to use.

Thank you for your response.

I like the sample code using cmd /c exit.

May I have sample sample usage and output of the bat file that you just posted related to my post?

And I already downloaded the command line calculator however I don't know how to use it to convert ascii code to it's value and string or char to ascii code.

CHARLIB - gives general help
CHARLIB HELP - lists available commands
CHARLIB HELP ASC - gives detailed help about the ASC command

Here is one simple script to convert ASCII code 65 to character A and back again

Finally, the end of CHARLIB.BAT (look at the source), is a TEST routine that exercises all the functions. Lots of examples there.

--------------------------------

I recommend renaming the command line calculator CALC.EXE to CLC.EXE so it is not confused with the Microsoft calculator.

The complete list of AutoIt functions is here: http://www.autoitscript.com/autoit3/docs/functions.htm
I think most of the functions are available in CLC.EXE

Sample usage:

To get results in variables:
The closing ) in the CLC function call must be escaped as shown.

Thank you dbenham i appreciate your help.

All my questions regarding this are answered.

I'm hoping to get more tips from you.
