zasm: reuse code from core 2019-04-17 07:00:19 +10:00			`; * JUMP TABLE *`
zasm: remove JUMP_ prefixes They serve no purpose and make the code less flexible. 2019-05-17 23:50:11 +10:00			`strncmp .equ 0x03`

zasm: use blkdev IDs as input and output This will soon allow use to seek and tell on input, which is necessary for a second pass which is necessary for forward symbol references. This require making `blkSel` a bit more flexible. Rather than having one global selected blkdev, each app can select its own, in its own memory space. 2019-05-11 08:20:43 +10:00			`.equ USER_CODE 0x4800`
