hi,
My original post to you reads:
I dont normally use the 'shorthand' symbols, didnt recognise it.
How do you feel about the use of these symbols in your coding?.
I have always been advised not to use them as their meanings can vary from one asm to another?.

It was necessary to use the expression
"I dont normally use the 'shorthand' symbols"
If I had said,
"I dont normally use the 'assembler directives"........... that would be incorrect.

"How do you feel about the use of these symbols in your coding?."
No where do I say its 'code'.
Many engineers refer to the 'Source Code' as 'coding' or 'code listing'.

Extract from MPLAB:
Directives are assembler commands that appear in the source code but are not usually translated directly into opcodes. They are used to control the assembler: its input, output, and data allocation

"I have always been advised not to use them as their meanings can vary from one asm to another?."
Extract from MPLAB:
Many of the assembler directives have alternate names and formats. These may exist to provide backward compatibility with previous assemblers from Microchip and to be compatible with individual programming practices. If portable code is desired, it is recommended that programs be written using the specifications contained here.

Your Reply:
For that matter I don't see how correcting an error, which will only cause confusion, is in any way 'not straight' either. While you knew what you meant, and I knew what you meant, a beginner wouldn't know what you meant - so it's important to be accurate!.

Extract from your Tutorials:
For the full code, with the equates, variable declarations and look-up table, consult the code for the examples below.

As I have said before I dont mind constructive criticism, but what does irritate is 'nit picking' to score brownie points.

the oneMhz is fixed number and equ to .1000000/.200
which is the high oneMhz , and which is the low oneMhz

The higher one is the top 8 bits (of the 16 bit value) and the lower one if the bottom 8 bits.
