Hi Ada experts !!!
I have code running on two different machines. Is there any interface
which I can use structural data between these two machines. It is possible
that two machines have ADA compiler from two different vendors.
Thanx in advance for any help

Theoretically, you can use record representation clauses to specify the
exact data layout at bit-level. Theoretically because the compiler may still
add stuff to the record that it doesn't tell you about.
Different implementations may also have different ideas about bit numbering and
the like, but you can avoid that by checking appendix F of each compiler
manual.

Actually, it can get much worse than that. Different machines store
integers in different byte orders. Additionally, floating point numbers are
notoriously non-portable. The only way to guarentee that files are
portable is to make sure to use some consistent format for all data
types. The easiest portable method is to store all data as ascii
strings, although there may be a severe performance cost to this
approach.
