Draheim guidod@gmx.de | ## Block Words + extensions `BLOCK``( block-u -- block-addr )``[ANS]` => `"[ANS] FORTH"` load the specified block into a block buffer and return the address of that block buffer - see also `BUFFER` primitive code = [p4_block] `BUFFER``( block-u -- block-addr )``[ANS]` => `"[ANS] FORTH"` get the block buffer address for the specified block - if it had not been loaded already it is not filled with data from the disk unlike `BLOCK` does. primitive code = [p4_buffer] `FLUSH``( -- )``[ANS]` => `"[ANS] FORTH"` call `SAVE-BUFFERS` and then unassign all block buffers with `EMPTY-BUFFERS` primitive code = [p4_flush] `LOAD``( block-u -- ?? )``[FORTH]` => `"[ANS] FORTH"` `INTERPRET` the specified `BLOCK` primitive code = [p4_load] `SAVE-BUFFERS``( -- )``[ANS]` => `"[ANS] FORTH"` write all modified buffer to the disk, see `UPDATE` and `FLUSH` primitive code = [p4_save_buffers] `UPDATE``( -- )``[ANS]` => `"[ANS] FORTH"` mark the current block buffer as modified, see `FLUSH` primitive code = [p4_update] `EMPTY-BUFFERS``( -- )``[ANS]` => `"[ANS] FORTH"` unassign all block buffers, does not even `UPDATE` primitive code = [p4_empty_buffers] `LIST``( block-u -- )``[ANS]` => `"[ANS] FORTH"` display the block primitive code = [p4_list] `THRU``( block1-u block2-u -- )``[ANS]` => `"[ANS] FORTH"` `LOAD` a number of block in sequence. primitive code = [p4_thru]
