Hi gilles,

I'm not sure what kind of time out you need, but this LabTalk command

sec -p n;

pauses script execution for n seconds. In Origin C you can use

Sleep(N);

where N is in milliseconds.

Hi Mike
I wait a change on a status line during a data acquisition. If no change occures the loop does not finish. In C++ the function TIME() allows solving this problem with a test on time. This function is not in Origin C.
Thank you

Hi gilles,

Can't you use Sleep in a do or while loop and require a status change to exit the loop? Something like this...

do
{
Sleep(100);
} while (//-no status change-);

You can test time by using GetTickCount, and use either

Sleep(N);// Origin will wait, nothing can be done in Origin

or

LT_execute("set -p 0.5"); // you can still do other things in Origin while waiting

Thank you for all.
I am added the function time to Origin C with the header:

#include <common.h>
#pragma dll(c:\WINNT\SYSTEM32\Msvcrt)
typedef long time_t;
typedef long* ptime;

int __cdecl _inp(unsigned short port);
int __cdecl _outp(unsigned short port, int value);
time_t __cdecl time(ptime temps);

It is better to write

#pragma dll(msvcrt, system)

to avoid hard coded path to your msvcrt dll.
