BASICA/QuickBASIC BASICA/QuickBASIC
IBWRTIA IBWRTIA
Purpose: Write data asynchronously from integer array
Format:
BASICA and QuickBASIC Version 1.0:
Call IBWRTIA (BD%,IARR%(0),CNT%)
QuickBASIC Version 2.0 and 3.0:
Call IBWRTIA (BD%, VARPTR(IARR%(0)),
CNT%)
QuickBASIC Version 4.0:
Call IBWRTIA (BD%, IARR%(), CNT%)
Remarks: BD% specifies a device or an interface board. IARR% is an
array from which integer data is written. CNT% specifies
the maximum number of bytes to be written.
Write asynchronously CNT% bytes of integer data from
IARR% to the GPIB. The data is sent in low-byte, high-
byte order.
This is a special case of the IBWRTA function, which
writes, in BASICA, a maximum of 255 bytes from a
character string to the GPIB. In QuickBASIC, this function
writes a maximum of 32 K bytes of data from a character
string to the GPIB.
Refer to the IBWRTA function and to the information about
BASICA/QuickBASIC GPIB I/O Functions at the beginning
of this section.
