[PIC] How do I access special characters in Standard Character Pattern

[Ernie H]

I'm trying to call from a subroutine the '!' exclamation mark character, in my assembly code i've made the subroutine for the exclamation character, like the letters i've been using to display on my 2 line LCD Alphanumeric screen, but when i compile the project is says illegal character, the compiler doesn't seem to want to display that character, but is fine with normal letters.

Thanks.
Ernie.

At least characters between 0x20 and 0x7f are printable in any character table, so is 0x21 = '!' Show the respective code line.
