16 | asm() takes a string of assembly code and produces a list of | |
17 | instruction words. When asm() is passed a list of strings it | |
18 | will produce a list of list of instruction words. For example | |
19 | asm('done;nop') returns [0x81f00000,0x1000000] and | |
20 | asm(['done','nop']) returns [[0x81f00000],[0x1000000]]. | |
