asdf is a minimalistic language with only 4 instructions.
If we want to print a character, we need to switch the bit twice by the instruction a (aa) while in memory cell #1 (initially we are in cell #3). Then a bit from cell #2 will be written to the memory buffer. As soon as 8 bits are accumulated in the buffer, the character with the corresponding ASCII code will be output to the console.
Our main task is to form the desired bit value in memory cell #2. The universal way is the sequence of sssas instructions. The only thing, before its first use it's necessary to move to cell #-1.
s -1 -> 0
s 0 -> 1
s 1 -> 2
a Toggle the bit (0 -> 1 or 1 -> 0) and set the toggle flag
s 2 -> 1 (in the opposite direction, since the toggle flag is set), clear toggle flag
Now we are in cell #1. Wrote the contents of the bit in cell #2 with the aa commands (they also set the toggle flag) to the buffer and again execute the same sequence.
s 1 -> 0 (toggle flag set), clear toggle flag
s 0 -> 1
s 1 -> 2
a toggle the bit, set toggle flag
s 2 -> 1, clear toggle flag
As you can see, we entered the cycle. If we want to toggle the bit and write it to the buffer, we execute the sequence sssasaa, if we want to write the same bit to the buffer - just execute aa.
From now on, we know what to do, so we create the source (for convenience, the formation of individual bits is divided by |):
|asaasaa|sssasaa| aa|sssasaa| aa| aa| aa|sssasaa| print 'a' (01100001)
|sssasaa|sssasaa| aa| aa|sssasaa| aa|sssasaa| aa| print 's' (01110011)

|sssasaa|sssasaa| aa|sssasaa|sssasaa| aa|sssasaa|sssasaa| print 'm' (01101101)
However, the language has one nice feature that will allow us to shorten this source in the general source code: it is case insensitive, which allows using 2 symbols per 1 instruction (a/A, s/S). After embedding the source code will look like this:

Unfortunately, not one online interpreter of asdf exists, so you can check only on the author's interpreter (local copy).
Go ahead, conquer the second language of the same author.
