Change bit in a byte?

[motorko2 (tom)]

I want to change a bit whose location in a byte I choose, whose value I choose.

Example:
~ I have byte:
10000000
~ I write at location 3 bit 1
and the byte should become
10001000

I tried this, with no luck:

You mean like this,

I have divide the length into two half and worked but if the procedure want to repeat for particular length then have to work a few more with the blocks

Or look for this extension

Number Converter Extension-Decimal,Binary,Hexadecimal and Octal Conversion

Name of Extension Number Converter Write a short description My second extension, Number Converter helps you for the conversion of binary, decimal, hexadecimal and octal number into any of this type. Add a picture of all the blocks 1) To Convert Decimal Number to Binary Number [component_method (4)] It helps you to convert Decimal Number to Binary Number. Remember It always accepts Integer value. 2) To Convert Decimal Number to Octal Number [component_method (5)] It helps you to conver…

But this will convert dec to binary

your blocks only seem to work if i want to change bit value at a predefined location,
but i want to be able to change the bit in a byte whose position I choose, and whose value (1 or 0) i choose

i need something like this: bitWrite() - Arduino Reference

btw that addon only does conversion
