Actually it is saying : The op.sys.refuses to provide memory,
Stata has already allocated 1584m bytes and is attempt to allocate 16m bytes. The operating system said no.
If you are using 32bit system then it is not possible to open such huge size of data (max ~2GB can be handled) .

I hope you have consulted this page already if not:

yes, I've already consulted it.
My computer is 32 bit! yes,May be should be the reason!!!!!!
Now, do I have to format the computer and make it 64 bit?
Upgrade is not possible, so yes, a clean install is mandatory.
Or, you could install a 64 bit version of OS in a virtual machine so that you will not have to format and reinstall everything.
Alternatively, do you need all 177 variables in memory at the same time? You could try just loading up the variables that you need, and that might fit within your system limits.
you can not make your computer 64bit. The hardware have to support 64bit OS. If it dose not support 64bit OS then you have the above suggestions or you can go for new 64bit computer..
Considering that the last models of 32bit processors were marketed 10 years ago, there is a high chance for the hardware support 64 bit OS.
Thank you all for your assisatnace!
Following instructions of 64 bit OS, I managed to open the dataset....Only
when operating with commands...It's slowing and Slowing! but
i have to wait....
Glad to hear you solved your problem. Hope you'll get you results.
Now that you opened it, it would be a good idea to limit the number of variables only to the ones you are interested at a certain moment (if that is possible).
How? When you open up a dataset, all variables are opened and activited
i don't know if this can be possible...
You think about analysing x,y, and z variables. You select all the other ones and delete them. Then save the file with a different name, and when conducting the analysis it should go faster.
If you are ok with what you have (in terms of time you have to wait to see a result), then forget about this idea.
Also remember to use the COMPRESS command after opening the file. It can really make the difference if the software that created the file did it in an inefficient way. For instance SPSS created Stata datasets tends to shrink by 70% or so when using compress.
Use the "set memory " command. Increase the putted size until all data appears.
