Re: st: issue with forvalues/foreach

[William Buchanan <william@williambuchanan.net>]

Hi Ivica,

Try:

forv i = 1/30 {
	use `"F:/project/data/dataset_`i'"', clear
	compress var1 var2
	save `"F:/project/data/dataset_`i'b"', replace
	clear
}

It's probably a good idea not to permanently modify your data files (so adding "b" to the end of the filename should make it easier to distinguish the two).  Also notice the use of "/" instead of "\" in the file path.  Using the "/" character will work on all platforms, and avoids some of the problems that you faced.

HTH,
Billy
