I would appreciate sharing knowledge on the issue of compiled local variables. The only reference I have seen is in the AUR manual and in some references on the 48 series. A simple example of an attempt to pass on a closed solution to an integration as a function to be called at will reveals some problems to me, but probably not to some of you more brlliant people. I can solve the problem by brute force, i.e., by changing every instance of "x"to the symbol for compiled local x manually, but there must be some way to generate rhe function directly.
The method I use now is to place the expression in a variable as a stored algebraic object recognising it as such by enclosing it between single quotes . The callimg routine has its independent variable placed on the stack in the proper position and calls lt as a compiled local, not just local.
FYI, I have tried temporary change of the CAS independent to the compiled version of x and to use it as the variable of integration, no can do. Thanks, Ron
