Is there anyone who has experience in using random access file types on
a Sun 3/50, with only the standard Berkeley (Sun) Pascal present.

This is my problem :

I am porting some Pascal (AOS/VS pascal - from some Data General Machine)
code to our Sun 3/50 environment. 
The Pascal code uses 'random acces' file types. 
Berkeley (Sun) compiler does not support this. 

I was thinking of the following solutions :
-----------------------------------------
- Rewrite the file handling parts in C. 
  Problems : . file parameter passing between C and Pascal functions
             . the C and Pascal file structure is very different.

- Loading the complete file into memory.
  Problems : . de file has a size of about 16 megabyte. (Slowwwww)
             

Anyone out there who can suggest other solution, or has comments on 
my ideas ??
