2 THE BASICS OF AD51H-BASIC
• When writing 32-bit data, the data is first set in array variables of integer format
using CDBI and CSNI instructions, then written to each device.
Example
100 DIM A%(1)
110 CDBI 123456!,A%(0)
• • • • •
“123456” is handled as 32-bit
data and the lower 16-bits of data
are stored in A%(0) and the upper
16-bits of data are stored in
A%(1).
120 W@(ED,102)=A%(0)
130 W@(ED,103)=A%(1)
• • • • •
The lower 16-bits of data stored in
A%(0) is written to ED102, and
the upper 16-bits of data stored in
A%(1) is written to ED103.
The internal word devices ED can be read from and written
to using the PUTMEM and GETMEM instructions, instead
of the special variables.
See Section 8.5.1, description of PUTMEM and GETMEM
instructions for details.
