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'

Calculating fb(x) number = 1

- 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']

{err}__00000N not found

{txt} matrix A[`i',1]=(1/(`nblack'*`hb'))*`sumttb'[`nblack']

This would be a reference to a temporary name which Stata regards as unassigned. I can't immediately imagine why this would have been broken by a change from Stata 5 to Stata 6, but it is difficult to debug blindfold. You could . set trace on and show us some or all of the log file up until it crashes. This might be shorter than the original program.
