This is a somewhat out-of-the-box question.
Usually in a program script you can call functions in a DLL by just typing their name: tccomdllo0001.do.check.this.bp(tccom001.bpid)
What I want to try is this:
In a fixed program (once compiled) I want to be able to extend its functionality and call newer DLL functions without touching the caller program.
I think it is impossible, since you need this "function call" in the object "used functions". On the other hand, is the PCF not more or less doing the same?
So I want to put the name of the function to be called from a (set of) DLLs
(which are declared = #pragma used dll "ofunction_library") in a variable.

In this way you can call any pre-programmed function for any file-type depending on the content of the program string variables VAR_FILETYPE_1, FUNCTION_FILETYPE_1 and FUNC_ARG_LIST_1.
It is a bit similar to what you can do with program variables
It is a bit similar to
except that also the name of the variable is variable... to a certain extend (as is its datatype due to implicit conversion).
The named program variable in tccom905.pvid must be pre-known in the program script and declared extern, but its value and its name can be set in a parameterized table tccom905.
Your first question would be: why would you want this?
hmmm you made me thinking like :confused:

Code:

tccomdll.&FUNCTION_FILETYPE_1(FUNC_ARG_LIST_1) then
