Dear Statalist members,
How can I replace characters at specific locations within an 
eight-character string?
I'm using -todate- with mostly good success to convert an 
eight-character string to Stata date, except when a month or day 
within that string is unknown. That would be coded "99", as in:
	"01991994", for "some day in January, 1994"
I'd like to edit that string to "01011994". Can this be done?
Tangentially, my code is:
	todate datevar, gen(newdatevar) p(mmddyyyy) f(%dd_m_cy)
	format datechemo %d
Thank you,
Michael
