# 1-> a ... 26->z

# from 96 lower case

# from 65 upper case

number=1

eval "echo \$'\\$(printf %o "$[$number+65]")'"

number=$number+1

eval "echo \$'\\$(printf %o "$[$number+96]")'"

# hum ...

echo uppercase("a")

Great it works !

For alphabetical in upper case, is there any fonction ,or I have to start
from 65 in hexa.

# hum .
I cas u do a simple loop, with a for statement like in c.


thanks.
