メモリーに関する命令

初期化に関するもの

INIT "dev:","spec"[,size]

dev=S1|S2

spec=M|F|P where M=extended memory, F=file device, P=program module

size=2..32 even integer, program module size in KB, remaining area is used as extended memory, available on either S1 or S2 on spec="P"

INIT "dev:"

dev=X to initialize diskette

INIT "dev:",size

dev=COM1|COM2

size=buffer size in byte, recommended size is >= 80 (<=9600 bps), 130 (19200 bps), 1100 (38400 bps)

NEW "dev:"[,size]

dev=S0|S1|S2 where S0=internal memory

size=reserved memory size from top of specified module, never used by BASIC interpreter (remember +0..+C5h is used as header and RSV)

メモリーアクセスに関するもの

PEEK(addr)

returns the content of address addr of current bank

PEEK#(bank, addr)

returns the content of address addr of specified bank, where bank=0..7

POKE [#bank,]addr,val[,val]*

poke value(s) into memory area beginning at address in specified bank where default bank is 0

CALL [#bank,]addr[,var]

if var is an integer (-32768..+32767): call with DE=value of var, returns DE into var if C=1

if var is a string: call with DE:B=address:length of value of var, returns DE:B into var if C=1

プログラムの入出力に関するもの

SAVE [*]"dev:fnam"[,A]

*:save BASIC program remarks as text excluding line numbers and remark symbols

,A:save whole BASIC program as text including line numbers

dev=S0|S1|S2|X|Y|COM|COM1|COM2|CAS

fnam=8.3 style file name

BSAVE "dev:fnam",sadr,eadr[,xadr]

dev=S0|S1|S2|X|Y|COM|COM1|COM2|CAS

fnam=8.3 style file name

sadr=0..&FFFF as start address of memory region to save

eadr=0..&FFFF as end address of memory region to save

xadr=0..&FFFF as executing address when loaded without specifying address to load

LOAD [*]"dev:fnam"

BLOAD "dev:fnam"

シリアルポートに関する命令

設定に関するもの

SETCOM "dev:"[,baud[,charbits[,parity[,stopbits[,xonxoff[,siso]]]]]]

dev=COM1|COM2|COM(current COM port, selected with SETDEV)

baud=50..38400, charbits=5..8, parity=N/O/E, stopbits=1..2, xonxoff=X/N, siso=S/N

SETDEV "dev:"[,spec]*

dev=COM1|COM2|COM(current COM port)

spec=PO/KI (no spec --> change current COM port)

送信に関するもの

SNDSTAT "dev:",prot,timeout

dev=COM1|COM2|COM(current COM port, selected with SETDEV)

prot:&00..&FF, meaning of every bit is as followings: 0='must be high (space)', 1='must be low (mark)'

timeout: 0..255, 1=0.5s, 0=forever

OUTSTAT "dev:",code

dev=COM1|COM2|COM(current COM port, selected with SETDEV)

code=0..3, meaning of every bit is as followings: 0='high (space)', 1='low (mark)'
