INTEXT: Stata module to read text files into string variables

The intext package inputs arbitrary text files into string variables in the memory, without removing leading and trailing blanks (as infix does). intext contains 2 programs, intext and tfconcat. intext inputs a single text file into a list of generated string variables, generating enough variables to contain the longest input text line (including leading and trailing blanks). tfconcat concatenates a list of arbitrary text files into a new Stata data set in memory, overwriting any previous data. The new data set contains a list of string variables (as generated by intext), and also, optionally, additional variables, indicating, for each observation, its input text file of origin and/or its sequential order as a line within its input text file of origin. Therefore, tfconcat is like dsconcat, except that it concatenates text files instead of Stata data sets. intext is an inverse of outfile,runtogether, because the generated string variables created by intext can be output using outfile,runtogether to produce a duplicate of the original file. Therefore, intext enables Stata programs to read Stata programs, just as outfile,runtogether enables Stata programs to write Stata programs.
