The idea with replacing separators in a text editor is good, but might be quite difficult for 600 files that Denisa has. It can be automated of course, say with a macro in Word, but why not to write the whole conversion in another programming environment? The final files will not be used in Stata, will they? 2Friedrich: insheet does not solve the problem in my view, beacuse Stata will still be limited to 244 symbols for strings. 2Denisa: please specify exactly, what are the rules for commas and "|" and missings in the input file.

(here is just a simpe example, the text in a cell could go up to 200 words of 30 characters each, and I have 15 of these variables, and 600 files...)Thanks ! > > > > Denisa > > University of Illinois Urbana-Champaign > * > * For searches and help try: > * http://www.stata.com/support/faqs/res/findit.html > * http://www.stata.com/support/statalist/faq > * http://www.ats.ucla.edu/stat/stata/ > * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
