As some might know I'm currently working on an SH3 assembler designed primarily around the Prizm. I do need to make sure that I have included all common assembler directives that you use whether it is in computer or calc coding. Here is a list of what I currently have.
#include
#define
.org
data.b
data.w
data.l
align.2
align.4
What I think I'm missing is some of the conditional pre-compiler directives which I will need to add. The other I'm looking for is the symbol used to indicate a new line. I know in C/C++ it is the ; but that is the comment in asm. Also anything else I'm missing would be good to know.

.org. Is good to use too, same with .reallocate
And there are others, but most people don't use them much, and still they're mostly used for z80 assembly development.

; actually isn't a new-line character. And there are two new line characters, one is 1 byte, one is two. One is a line-break and feed I believe, the other is just a line break.
The 1 byte one is 0x0A, the 2 byte one is 0x0D0A

Ashbad, I can't find the meaning of .reallocate anywhere. What does that do? And the .org was my bad there. But actually unlike on the z80, most people will not use .org because most SH3 code is location independent and I've also been pushing for shell-cross compatibility for all prizm programs.; actually isn't a new-line character.

I was just mentioning how in C/C++ you can start a new line using a ; but that is already reserved in asm for indicating a comment. What I'm looking for is the character allowing you to use multiple commands in one line.

Oh, probably \. That's what it usually is, IIRC.

well, reallocate can be used to change the location of where the address labels and such are being offsetted form, like .org -- but you can use it at any time, whereas with many assemblers, .org doesn't function that way.
