- Why hasn't Ada caught on in engineering? Well one big reason is cost.
-
- A little while ago, I was involved in flight simulation and we were
- facing customer pressure to abandon FORTRAN and go to Ada.
-
- Actually, the pressure wasn't very great. The Statements of Requirements
- always said "A High Level Programming Language will be Used, preferably
- Ada".
-
- Well, I believe that Ada has many advantages over Ada and, of course
- 'C' (which is the other language we used), so I was keen to aid the
- change. (In fact I ended up managing the first Ada project we did.)
-
- So what did I mean by cost? Well, apart from the training costs
- and the cost of setting up development systems that actually used
- Ada, (New compiler driving scripts, new way of addressing hardware,
- new way of managing "global variables" - Yes, nasty as they are,
- you do sometimes have to use global variables in the real world!)
- there was a nasty shock in the price of the compilers.
-
- What do I mean by nasty? Well, we were able to use a FORTRAN
- compiler on our systems for a cost of $2000 per project.
- (ie per host processor.)
-
- The Ada compiler vendors wanted $30 000 PER SEAT. We even
- had the vendors charging different prices for the same compiler
- on different hosts. ie. A compiler/toolset on a Sun SPARC 1 was
- $30 000, while on a Sparc 2, the same software was $40 000.
-
- The attitude of the vendors was "We know you've GOT to use Ada,
- so just hand over the blank cheque and we'll let you."
-
- They were, of course, wrong. The cost (in parerwork etc.)
- of getting Ada waivers was generally less than the cost of
- the compilers - let alone the training costs etc.
-
- So what do my previous employers do now? Well they still
- use FORTRAN and C, and they fight any requirement to use
- Ada. It just costs too much, and when it comes to it,
- their customers - even the military ones - place
- their orders on price; Ada is still on the wish list.
-
- So, if you want the Ada market to grow, compiler
- vendors, get your prices down!
