BASICA/QuickBASIC BASICA/QuickBASIC
IBRDI IBRDI
Purpose: Read data to integer array
Format:
BASICA and QuickBASIC Version 1.0:
Call IBRDI (BD%,IARR%(0),CNT%)
QuickBASIC Version 2.0 and 3.0:
Call IBRDI (BD%, VARPTR(IARR%(0)), CNT%)
QuickBASIC Version 4.0:
Call IBRDI (BD%, IARR%(), CNT%)
Remarks: BD% specifies a device or an interface board. IARR%
specifies an integer array into which data is read from the
GPIB.
CNT% specifies the maximum number of bytes to be
read. VARPTR returns the address of the array so that it
may be passed to the language interface.
Read up to CNT% bytes of data from BD% and store in
IARR% . As the data is read, each byte pair is treated as an
integer and stored in IARR% .
Unlike IBRD , because IBRDI stores the data directly into
an integer array, no integer conversion is needed on the
data that has been read for arithmetic operations to be
performed on it.
Refer to the IBRD function and to the information about
BASICA and QuickBASIC GPIB-PC I/O Functions at the
beginning of this section.
