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