I want to create a structure with BoundedStrings (two of them, just a few bytes long)

I want it to look like this:

Code:
Public Structure CID
   Public MID   as byte
   Public OID   as UnsignedInteger
   Public PNM   as BoundedString(6)
   Public PRev   as byte
   Public SerNum   as UnsignedLong
   Public MDT   as BoundedString(7)
End Structure


I want to allocate the structure in the main program, then fill the structure in a subroutine.

I allocate it like this:
Code:
Dim CIDInfo as CID


I want to pass it like this:

Code:
Public Sub MMCInfo(byRef CIDInfo as CID)


And when I do it, I get this error

Code:
Internal error: variable.cpp(2576), Rev 674: unsupported Based type, "MMC_API.bas" line 135


Are BoundedStrings not legal in a structure?


--------- As I test this further, it seems that I can not actually assign characters to the structures string element with the statement

Code:
CIDInfo.PNM = "test"


This is what generates the error code

Upon further testing, the structure is fine.

The problem occurs when passing it to the subroutine.

How does one pass a reference to a structure to a subroutine legally?

Just as you have done. The problem only occurs when referencing string types in a structure passed to a procedure. This is another symptom of the problem that Steve reported yesterday. It has already been fixed.

I suspected that Steve's problem might be related to mine. I worked around it with global variables for now.
