What does Stata do when it reaches the end of Know that when we use the file read command, Stata reads lines one a time, and that each time we ask it to read a line, file open myfile using "d:filelist.txt", readįew more things you need to know in order for the code below to make sense. myfile), and finally,īy giving Stata the name of the local macro into which we want to place the information Read), followed by the name of the file (i.e. ![]() file), then the action we want to perform on the file (i.e. Read a line from the file we have called myfile by starting with theĬommand (i.e. The second line of code below tells Stata to We tell Stata to read from that file, it will read the next line, and so forth That line is placed in a local macro which the user can then access. Single line and stops (unless we tell it to do otherwise). When Stata "reads" a line from a file it reads a The next line of syntax reads the first line of the file we have named Getting information from, but not adding information to) the file. ![]() Specify read which tells Stata that we are going to be reading (i.e. Name tells Stata where the text file we want to read is located. The word using followed by a file path and Instructs Stata to open a file ( file open), and assigns it the name myfile. We are referring to with any given command. One file open at a time, meaning that we need some way to tell Stata which file It is necessary to assign each file a name because it is possible to have more than Open) is followed by a name that is used to identify the text file (known as a handle).Īll of this is followed by something else, depending on what we are doing with the file.Įach open file has a name associated with it, (in our example theįile is called myfile). We want to perform (in this case, open the file). With the command file, followed by the type of operation These commands allow us to read and/or write information from text files. Stata has a group of commands all of which start with the command file, If we open the text file, it looks like this: This is the first line With a file named (click here to download: ), it has seven lines of text that we want toĭisplay in Stata. ![]() Our example reads in information from a text file, and displays it in Stata. Way you would treat a dataset, then it is appropriate to use file read. Not formatted the way a dataset would be, or that you do not want to treat the List of some sort in a text file, or some other type of information, which is Note that if you are trying to read in a dataset in ascii format,Īnother command, such as infile or insheet is probably more appropriate. The file read command can be used to read information from an external
