Get a 62.5% more program space easily

interesting idea if you only need plain text in Upper Case. Good job! Now how do you save this to your codespace?

Did you already look here for a thread called Embedded String in your code space?

Easier does it?

In fact it's possible to use any character using a 5bits coding:

Since A-Z is only 26 letters, the 5 bits coding has a remaining 5 position to be used as controls like bellow:

I prefer to use the default as a lower case chars. (abcdef...)
So A-Z are coded as a=1, b=2, c=3, d=4...till z=26

As controls I use:
0 - End of string
27 - Space char
28 - Begin/End mark for a upper case string
29 - Begin/End mark for numbers 0-9
30 - Begin/End mark for symbols +-,.!$%^ (max 26 symbols each one is a char A-Z)
31 - Reserved, I have in nothing in mind in the moment :-)

So I code the string this way:

Source:
"/t/hese /word/ is in upper case this year is [bjjf]"

the ouput:
"This WORD is in upper case this year is 2006"

I am doing this ... errr... by hand :-) transforming the string directly to bits, it's a hell of work i know, I need just to create a program to translate the strings (Source above) to the bits and coded as i want.

Well, this idea I took from the HTML format, so even with as little as 5 bits I can get any char in a compact size :-)

with the previous link, it will take the same code space (+/- few bytes) and you'll never have to translate your strings. Make things really much easy when you need to modify or add any strings.

Another idea is to save your string (or part of) in the internal EEPROM. Using your method or a variant of will permit to store 256 character in the internal EEPROM. I don't know how your string eat space but it could work too.
