I am restating my question about outputing specific voltage values

Question

Hello,
Right now, I use the function generator vi , an example vi from DAQ and analog out. So from that VI i get functions such as sine, sqaure with a user defined amplitude and frequency. Now what i want to do is this:
Develop a vi which will output specific voltage values defined by the user (me). i.e, say i want the vi to output voltage values such as 0.1,0.2,0.3,4,6,8,10,12,14,0.4,0.5, then i just write these values in the table and the vi should ouput these voltage values one after the other in near real time. I hope i am clearer this time.
I am an amatuer user of Labview and am currently working on a student version of Labview 7.0 Express.
Thank you

Thanks for the reply.
Yes, i think you have understood my problem correctly now. But the only thing i would like to clarify is that I would input the voltage values before starting the program, say in the form of a array/table. Once i put these values the program should output these voltage values. These voltage levels should be output in near real time i.e., the time between two values should be in the microsecond domain.
Here are the sample voltage levels I am interested in. ( but i want these values alterable, i.e., i should be able to input these values before running the vi)
Voltage Levels(V)
0.1
0.2
0.3
0.4
15.0
-15.0
0.5
0.6
0.7
0.8
0.9
1.0
1.1
1.2
1.3
1.4
1.5
1.6
1.7
1.8
1.9
2.0
The time lag between two levels should be preferably as less as possible in microseconds. I am not able to tell you any specific value, but 5-10 microseconds should be fine.
Just a query: Can this whole thing be achieved by reading this from a file by changing the interface of the existing function generator vi to a read from file ( spreadsheet). I tried this but the parameters of inputs in the program didnt match and hence the vi failed to run. Is this a possible approach though?
