Hi,
now that I have written this little widget "calculator" which works
really fine and computes almost anything I want (which is not much
more than the occasional +,-,*,/ or logarithm, I must admit), I am
slowly getting sick of clicking my way through a bit more nested
formulas, especially when I have to repeat the same calculation with
different data sets. I already designed my calculator to return a
formatted string describing the arithmetic operations that it performed,
but now I am looking for a way to read these strings back in and do
calculations as a batch job. Is there any way to use the build in parser
of IDL ? Or has anyone written something like this (which is well enough
documented so that I could adapt it to my needs) ? I have also briefly
thought about writing out the equations in a file tmp_func.pro or
something alike, and then use EXECUTE (or whatever would serve the
purpose) in order to compile and call the procedure/function that has
been automatically produced.
Any ideas appreciated,
Thanks,
Martin.
