BPI_READ
B-7
BASIC Example
The BASIC function code is 34.
Important: For BASIC, the data type for the inbuff and trgmask
parameters is INTEGER. There is no byte-type constant; therefore,
byte-type variables must be used to pass the byte-type information.
DIM status,timeout,inbuff(32),trgmask : INTEGER
DIM size : BYTE
.
.
.
timeout=4
trgmask=4
size=6
.
.
RUN AB_BAS(34,status,size,ADDR(inbuff(1)),timeout,trgmask)
.
