And in that case it would be quite straightforward to build up the macro to be written with a forvalues loop over the variables to be written, allowing such a routine to accept a varlist of indeterminate length and generate the desired single-space-delimited output. However, when using space delimiting, one must always worry about string variables with embedded spaces. If there is no risk of that, this would work quite nicely. Here is a quick and dirty hack that nevertheless seems to work (well, watch out for string variables):With the file command, you can roll your own version of this fairly easily: version 6 file open myfile using <filename>, text write replace local N=_N forval i=1/`N' { local line : di _col(1) varname1[`i'] _col(25) varname2[`i'] ... file write myfile `"`line'"' _n } file close myfile version 7I should note that the original request was for a single space between variables -- then the fifth line would look like this: local line : di varname1[`i'] " " varname2[`i'] " " varname3[`i'] ...
