I need the ability to access Pascal Libraries from C mainlines and
functions. My goal currently is to produce a C/Pascal interface document. 
I am currently on a Vax 11/780 running 4:3 BSD UNIX.

The first phase of my investigation is complete and its description
follows. I have produced a number of test cases involving the simple 
ordinal types:

boolean
char
integer
real

For each of these types, I have a test case of a C mainline:

1. calling a pascal procedure with the value
2. calling a pascal procedure with the addreses of the value
3. calling a pascal function with the value
4. calling a pascal function with the addreses of the value
5. calling a function which  returns the value
6. calling a pascal procedure with a pointer to an array of the values
7. passing a pascal procedure a pointer to a structure which contains
   these values (unpacked)

These tests all work as expected.

The second phase of my investigation is to produce tests involving
these remaining Pascal data types and features:

8. variant records
9. user defined ordinal types
10. sub-ranges
11. packed arrays
12. packed records
13. nested records
14. sets
15. non-zero based arrays
16. the use of malloc vrs new   
17. proper building of makefiles for compiling
18. file opening, closing, and accessing
19. What haven't I thought of??

To test these it seems I would need to know the feature's implementation.

Any help would be appriciated.
