That _did_ work. Thanks.

I had a jsp.ijs that I thought was that one. It's got a section
,----
| NB. Differentiation and integration
| D=. ("0)(D. 1)
| W=. +:(#.|[EMAIL PROTECTED])"0 1|:@(0:,%.@(^/[EMAIL PROTECTED])%>:@i=.
i.@>:@+:)
| ew=. +/@(-@(<:@([EMAIL PROTECTED])[EMAIL PROTECTED])|."0
1]{.~>:@([*<:@([EMAIL PROTECTED])))
| EW=. ([ ew [EMAIL PROTECTED]) f.
| ai=. 2 : 0
| ai=. +/@(x&space * x&[ * y@(x&grid))"0
| )
| grid=. space [EMAIL PROTECTED]@[
| space=. ] % <:@[EMAIL PROTECTED]
| I=. (4 EW 5) ai
`----
that looks a lot like http://www.cs.ualberta.ca/~smillie/Jpage/jsp.ijs,
but it's clearly not identical. The "offending" section includes
,----
| NB. Probability distributions
| cdf=. 1 : 0
| +/ @ ([ x f. (i. @ >: @ ]))
| )
| binomial=. (x!n) * (p^x) * ([EMAIL PROTECTED] {:@[) ^ ([EMAIL PROTECTED]) -
x=. ] f.
| BINOMIAL=. binomial cdf
| poisson=. [EMAIL PROTECTED]@[ * ^ % [EMAIL PROTECTED]
| POISSON=. poisson cdf
`----
Note that the cdf adverb makes the distribution into an (uppercase)
cdf. I don't see that in the current version; I must have had a really
old one. I somehow thought it was the same. BTW, the file I had has no
header at the start; it just begins
,----
| NB. General-purpose verbs
| B=. *&G % [EMAIL PROTECTED]
| BoxSort=. /:>
| COMB=. ([ comb [EMAIL PROTECTED]) { ]
`----
Thanks again,
Bill
