IBM provides ILE compilers for C, C++, RPG, COBOL and CL. [1] For RPG, COBOL and CL, there are both OPM compilers (still sometimes used for legacy applications) and the new ILE compilers. Likewise, as well as ILE C, there was an earlier EPM-based C/400, although that has been discontinued.
COBOL as defined in the original specification, possessed excellent self-documenting capabilities, good file handling methods, and exceptionally good data typing for the time [.] COBOL programs are in use globally in governmental and military agencies [...] and on IBM's z/OS, Microsoft's Windows, and the Unix/Linux families.
In this C# example, all exceptions are caught regardless of type, and a new generic exception is thrown, keeping only the message of the original exception. The original stacktrace is lost, along with the type of the original exception, any exception for which the original exception was a wrapper, and any other information captured in the ...
The implementation of exception handling in programming languages typically involves a fair amount of support from both a code generator and the runtime system accompanying a compiler. (It was the addition of exception handling to C++ that ended the useful lifetime of the original C++ compiler, Cfront. [18]) Two schemes are most common.
COBOL (/ ˈ k oʊ b ɒ l,-b ɔː l /; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and ...
An exception handling mechanism allows the procedure to raise an exception [2] if this precondition is violated, [1] for example if the procedure has been called on an abnormal set of arguments. The exception handling mechanism then handles the exception. [3] The precondition, and the definition of exception, is subjective.
PL/I exception handling, via ON-units, allowed the program to stay in control in the face of hardware or operating system exceptions and to recover debugging information before closing down more gracefully. As a program became properly debugged, most of the exception handling could be removed or disabled: this level of control became less ...
Use of IBM COBOL was so widespread that Capex Corporation, an independent software vendor, made a post-code generation phase object code optimizer for it. [3] The Capex Optimizer became a quite successful product. [4] Although the IBM COBOL Compiler Family web site [5] only mentions AIX, Linux, and z/OS, IBM still offers COBOL on z/VM and z/VSE.
