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.
