Thank you, Nick.
well, then the problem is somewhere else. my real question is about a
automatic log-creation program that i have run from a profile.do file at
stata startup, which has been malfunctioning.
my intent was to creat a log file with the name mmddhhmm.log, where mmdd
comes from $S_DATE and hhmm comes from $S_TIME. my program has looked
like this for years, and it has no longer been able to add the mmdd part
because my call to date("$S_DATE","dmy" returns missing value:
the program is below.
thanks for helping me out of this rut.

program define autolog
local logdir=".\logs\"
local logfile : display %dND date("$S_DATE","dmy")
substr("$S_TIME",1,2) substr("$S_TIME",4,2)
local logfile : display "`logdir'" substr("`logfile'",5,.)
".log"
capture log using `logfile'
if _rc==602 {
while _rc==602 {capture log using
`logfile'}
}
if _rc!=0 {
di in red "could not open logfile"
error _rc
}
di "----log file:`logfile'----"
end

Subject: st: RE: date function error?
No Stata error here, just a subtle misunderstanding.
Step 1. Stata substitutes macro names by their contents.
Step 2. -display- sees 12Jun and tries to make sense of it but fails.
12Jun is not a number, nor a variable name, nor a scalar name.
Solution: You need to spell out to Stata that you are dealing with a
string.
. di "$S_DATE"
does that.

Hoffman, George
i've got stata 10 on win32, and have been troubled by an error in the
date function:
. di $S_DATE
12Jun not found
r(111);
