Welcome and good to see you in the community! On the first question, you can open as many instances of Stata as your computer allows; or you can -append- or -merge- datasets. On the second, every time you open an instance of Stata, "a new dataset" is already there. -generate- as many variables as you like, -format- them and -save- them in .dta format. If you want to get file transfers, both in and out of Stata, right fast, I would recommend investing in Stat/Transfer which is great in combination with the -ssc describe stcmd- package. BTW, the red columns are string variables. Stata is not particularly fond of those, so most of the time you want to -decode- or -destring- them. After -destring-, they will be highlighted in blue in the Data Editor and Data Browser. Note that not all strings should be treated this way, though. If you have a dataset whose 250 rows are populated by the countries of the earth, you probably should leave the "country" variable as string...

I am really, really new to STATA and I am going to be using it to perform various kinds of data manipulation. Also, I have been a user of SAS in recent times so these questions mention SAS every now and then. In general, I found STATA to be quite user friendly with all the commands. I have been reading the manuals and a lot of online help sites so that's been good. However, here are a few questions I had: 1. STATA only opens one data set at a time, while SAS can open as many as you want in one window. How do you get around that problem? I ask because I will have to use multiple datasets at one time for sure. This is a concern and I am sure expert STATA users get around this "problem." 2. How do you create a blank dataset in STATA? In SAS, we have the data step where one can keep variables we want, format them, etc and then set them equal to whatever we want from some other data set. Mapping and creating new data sets is a bulk of what I do, hence this question. 3. What is the best way to import files into STATA. I am using the "insheet" command but I get a many "red" columns, all the time. 4. How do you format fixed width excel or TXT files in STATA? And, export them properly? In particular, format the fields to be a certain width, keep the leading zeros etc. Thanks so much. I really, really appreciate it, looking forward to all your answers. -Prash. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
