To run this program, Driver488/SUB must be installed and resident. Successful operation of this
program proves that the driver is installed and the Driver488/SUB subroutines were properly
linked to the application program. Errors in setting up board parameters like DMA channel and
interrupts will not be detected by this program.

For Turbo C++ and Borland C++ Users

•

Driver488/SUB supports four memory models: “small,” “medium,” “compact” and “large.” (See
the Sub-Chapter “Other Languages” in Chapter 8, for more information on memory models.)
Include the

iottx10.h

and

iot_main.h

header files in your program and link in proper

Driver488/SUB library files, as shown below:

iottx10s.lib

for small memory model programs.

iottx10m.lib

for medium memory model programs.

iottx10c.lib

for compact memory model programs.

iottx10l.lib

for large memory model programs.

•

Use the following command-line command to compile and link your program. For example, the
following commands create a compact model executable file using Turbo C++:

tcc -mc hello.c iottx10c.lib

tcc -c -mc hello.c
tlink hello.obj + c0c.obj,,,cc.lib iottx10c.lib

Similarly, these commands create a compact model executable file, using Borland C++:

bcc -mc hello.c iottx10c.lib

bcc -c -mc hello.c
tlink hello.obj + c0c.obj,,,c.lib iottx10c.lib

•

Use the example test program to query Driver488/SUB for its

Hello

message:

#include “iottx10.h”
#include “iot_main.h”
main ( ) {

DevHandleT ieee;
char response [100];

Hello (ieee, response);
printf (“--%s\n”, response);

}

Upon execution, the following response is printed on the screen:

-- Driver488 ver 4.0........

QuickBASIC

To successfully operate Driver488/SUB, a definition file must be included in the user’s application
program. This definition file can be found in the

\IEEE488\SUBAPI\QB45

subdirectory, if installed

under the default conditions.

In the same directory as the definition file, are the libraries needed to access Driver488/SUB from
QuickBASIC.
