I've seen ad's for C interpreters from a variety of places (cost
ranging from $129 to $500); do people out there have any significant
experience?? [Note that they all run on MSDOS machines, I haven't
seen ads for VAX based ones].
Key factors are: Any deviations from K&R? What libraries are supplied?
Can you include assembler programs? Size limitations of source code?
Of course price is no object { -) }.
If there's enough reponse and interest, I'll summarize and post.

For VAX, 3B2/300, 68000 and as well as proprietary architectures. It will also run on the PC under MD-DOS. The interpreter is called SMART/C**. What follows is from the data I have about SMARTC/C: The SMART/C Environment * Fully intergrated editor AND interpreter. * One command set. * Move between the editor and the interpreter at will. SMART/C syntax directed editor: * Full K & R standard. * Vi-like command set. * Automatically provides formats blocks, for, case and if statements. SMART/C Interpreter: * Current module can call external modules during interpretation. * Has include capability. * Totally precompilation - no incremental compile. * Can interpret partially defined files allowing for rapid prototyping. * Variable speed of interpretation. * Multiple windows with user define sizes. SMART/C Migrator: * Allows C code produces with any editor to be interpreted by SMART/C. * Reformats for readability. With reference to the Key factors questions above: SMART/C is a full K & R standard. Currently only the stdio library can be used. The next release thay say will handle used defined libraries. SMART/C does not support inline assembly code currently. As far as I am aware there is no limitation on size of source code. The only limitation is the disk size. Costs: SMART/C is available for the PC running MS-DOS for $495. The cost increases depending on the size of the machine, up to a VAX780 at, I understand to be $9995. SMART/C is available from: AGS Computers Inc., Advance Product Division, 1139 Spruce Drive, Mountainside, NJ, 07092. Phone # 1-800-AGS-1313 & (201)-654-4321. *UNIX is a trade mark of AT&T Bell Labs. **SMART/C is a trade mark of AGS Computers Inc. Comments? {ihnp4}whuxl!qtest

This strikes me as a bit too commercial, even for what is ostensibly a third party replying to a request for information. I would like to relate my experience with Smart/C. (I am the project head for a competing product, The Bcc Compiler -- a checkout compiler, not an interpreter.) I saw a demo of Smart/C at the April UNIX Systems Expo in San Franciso, and it was, in brief, a very slick toy. The syntax-directed editor either didn't handle preprocessor macros at all, or didn't handle macros such as ``#define forever for(;;)'' that do not expand to subexpressions. (The salesman had been given a line to handle complaints about this: he said, "you know, the preprocessor isn't part of the language." Wrong.) Printf and scanf were not handled. Libraries other than stdio were not handled. A test program which accessed storage beyond the end of an array crashed the interpreter. In the product's favor, it has an impressive user interface. But in the state I saw it, it won't run the average 10-line C program. Before it can be a real product, it will have to run the average 10,000-line C program. And that is quite a gap. *Most* of our product's development cycle was spent between these two stages. (And, yes, our product is ready and available now.) I am interested to hear, by mail or news, from anyone who has used a C interpreter under UNIX that runs a program of reasonable size and complexity. ------ Sam Kendall UUCP: {allegra,cmcl2,ihnp4}!delftcc!sam Delft Consulting Corp.
