Remote Program Examples using GPIB interface

7.6.1 Example Using Quick BASIC

'
GPIBEXAMPLE.BAS
'
' This sample program is for reference only. It can only be expected to
' function with a Digital Multimeter.
'
' This program reads 10 measurements from the meter and averages
' the sum.
'
' The status variables IBSTA%, IBERR%, and IBCNT% are defined in QBDECL.BAS.
' Each bit of IBSTA% and each value of IBERR% are defined in QBDECL.BAS as
' a mnemonic constant for easy recognition in application programs. In this
' example, these mnemonic definitions are logically ANDed with the variable
' IBSTA% to determine if a particular bit has been set. The mnemonic
' definitions are equated with the variable IBERR% to determine the error
' code.
'
' The subroutine GPIBERR is called when a NI-488 function fails. The
' error message is printed along with the status variables IBSTA%, IBERR%,
' and IBCNT%. The subroutine DVMERR is called when the serial poll response
