st: RE: Stata5 v Stata8

["Donal O'Neill" <doneill@may.ie>]

Nick,
Here is a copy of the trace file leading up to the error. There seems to be 
a problem with the way I am calling the matrices. I have included a 
"tempname A B C D J I J K" command and putting the resulting matrix names 
in single quotes but that made no difference.

....
....
- matrix A=J(50,1,0)
- matrix B=J(50,1,0)
- matrix C=J(50,1,0)
- matrix D=J(50,1,0)
- matrix H=J(50,1,0)
- matrix I=J(50,1,0)
- matrix J=J(50,1,0)
- matrix K=J(50,1,0)
- set more 1
- sum `wage'
- gen `m1x'=0.5-`hb'
- gen `rx'= 4-0.5+2*`hb'
- gen `ix' = `rx'/50
- gen `mx'=sum(`ix')+`m1x' +`ix'/2
- sum `wage' if race==1
- gen `m1y'=_result(5)-`hw'
- gen `ry'= _result(6)- _result(5)+2*`hw'
- gen `iy' = `ry'/50
- gen `my'=sum(`iy')+`m1y' +`iy'/2
- noi di "CALCULATING ADAPTIVE VALUES"
CALCULATING ADAPTIVE VALUES
- while `c1'<=50 {c -(}
- noi di "Calculating fb(x) number = " `c1'

- replace `xo'=`mx'[`c1']
- replace `zx'=(`xo'-`wage')/(`hb'*`winfacx')
- replace `ttb' =(1/(sqrt(2*_pi)))*exp(-.5*`zx'^2)
- replace `sumttb'=sum(`ttb'/`winfacx') if _n<=`nblack'
- replace `kzxx'=normprob(`zx') if _n<=`nblack'
- replace `sumx'=sum(`kzxx') if _n<=`nblack'
- local i = `c1'
- matrix H[`i',1]=(1/(`nblack'))*`sumx'[`nblack']
