I'm not sure I completely follow, but for a dataset that looks something like:
*********************begin example
clear
set obs 1000
g acuteall = rbinomial(1, .4)
forval n = 1/30 {
	g e`n' = rbinomial(1, .4)
	}
sa "test.dta", replace
****
/*
you say you want a" summary comparing the mean acuteall for each category of each of e1 thru e30..."
yet, e1-e30 are not categories.  I interpret this to mean you want the mean of acuteall when e1 ==1 and 
then e2==1 and so on, like:
*/
su acuteall if e1==1
di "`r(mean)'"  //notice this equals the first obs in the collapsed data below

**but for all vars...so you could collapse like:
g id = _n
reshape long e, i(id) j(ee )
keep if e==1
collapse (mean) acuteall,  by(ee)
**to get the mean of acute all where e* == 1
**now, you can list, outsheet, texsave etc this dataset as a table


**OR**
****** maybe you want something more like tabout(from SSC) has to offer(?):
u test.dta, clear
tabout e* using "test.txt", sum oneway ///
	replace c(mean acuteall) 
type "test.txt"

tabout e* acuteall using "test2.txt", ///
	replace c(col) f(1p)
type "test2.txt"
********************end example

Subject: st: tabstat upside down

all,

I have 30 binary variables (e1-e30) and I have another yes/no (0/1)
variable called acuteall; I want to supply my client with an easy to
follow summary comparing the mean acuteall for each category of each of
e1 thru e30; -tabstat-, however, supplies me with the mean of each of e1
thru e30 for each category of acuteall (command: -tabstat e1-e30,
by(acuteall)-)

in other words, in the following table, I want to see .122 v. .184 and
what I get instead is .04 v. .0634; suggestions more than welcome (I
could not see how to do this with -collapse- either, but maybe someone
else can)

. ta e1 acuteall, ro co nofreq
