292.0. "FOR/C argument passing" by TLSE01::SAAD () Wed Nov 28 1990 07:47

	VMS languages question :

	Is there a document or paper somewhere that summerizes 
    	the major differences between VAX FORTRAN and VAX C in 
        terms of argument data types (strings, arrays,..) 
        and passing mechanisms.
    

	Basically, our customer would like to avoid the potential 
    	pitfalls which he might encounter when calling C routines
        from FORTRAN.
                               
    
    	Thanks
    	William

292.1		TLE::FELDMAN	Larix decidua, var. decify	`Wed Nov 28 1990 13:25`	19
	Look at Chapter 13 of the Guide to VAX C (VAX C in the Common Language Environment) Chapter 6 of the VAX FORTRAN User Manual (VAX FORTRAN in the Common Language Environment) and, for more detail Chapter 2 of the Introduction to VMS System Routines (VAX Procedure Calling and Condition Handling Standard) I don't know of any quickie summary. The programmers or engineers doing the actual coding really ought to read both of the chapters mentioned above, and make sure they understand them. It's not terribly difficult stuff, but it's also not worth looking for shortcuts. Gary
292.2		BOMBE::PROBINSON	Just causing trouble...	`Thu Nov 29 1990 19:37`	5
	Years ago, there was such a comparison. It was a quick summary/comparison of every language available at the time, I believe including features and datatypes. I don't remember what it was called (I never actually obtained a copy, although someone in my neighborhood had one) and I'm sure that its like has not been produced anytime recently.
