Yes, I did. As an exercise I re-coded Phil Benkard's SUMROUND-function
(APL91 - Stanford) in Fortran90. The function was rounding of values to
a given number of decimals (or rather powers of 10) in the left arg, with the
requirement that the sum of the rounded off values should exactly equal the
rounded off sum of the bare values (e.g. as required in financial reports).
Executing the Fortran90 on 10000 values gave me time not only to get
and drink coffee, but even to collect and burn the beans.
That's why I stuck to APL.
An other funny story is that in some project the "programmer's team" wanted
to see Fortran code, while the work was already done in APL by the responsible
engineers satisfactorily (funny? silly? but true!).
The APL-people decided to write an APL code that produced the thing in
Fortran, so, they had their Fortran code (APL Toronto '93 - it's on video tape).
But why? How would you ever write, test and debug 20.000 lines of Fortran?
