Single character constants

David Betz

Is there a way to use single character constants in GAS? I think they are normally indicated by single quotes but we've repurposed those to introduce comments. Is there an alternate way to do character constants? I want to do something like this:

hello  byte	'H', 'e', 'l', 'l', 'o', ',', ' ', 'W', 'o', 'r', 'l', 'd', '!', 15, 12, 0

No, unfortunately there's no way to do single character constants in GAS. What you wanted though could be accomplished by something like:

hello ascii "Hello, World!"
        byte 15, 12, 0

Okay, thanks! That is what I was after.

Would something like

hello byte "H","e","l","l","o"
  ' etc...
  byte 0

also work?

No.

The single character version David originally posted would be the normal way to do this, but as he mentioned the single quote is co-opted for comments.

Perhaps we should revert GAS to using semicolon for comments, but that opens up a whole other can of worms regarding PASM compatibility, so perhaps not.
