GENERAL DESCRIPTION
The HLASM390C® translator is a software tool that will convert existing HLASM390 programs to "C". The powerful HLASM390C® translator accepts HLASM390 programs, checks their syntax and outputs C code. The comments are move transparently from the source file to the target file. Any built-in functions for math, string manipulation and I/O in HLASM390 are converted to calls to external procedures (Get free sample translation) .
The HLASM390C® translator contains a syntax analyzer, an HLASM390 to tertiary converter, and a tertiary to "C converter. The syntax analyzer scans the HLASM390 input file for syntactic errors and generates a listing file of the HLASM390 program. Any syntactic errors will be flagged with detailed English messages in the listing file. If no errors are encountered, the HLASM390 input file is converted to tertiary language. Then the tertiary file is checked and, if no errors are detected, it is converted to "C". A command line control is provided to allow translation with errors in the source file. This is helpful when translating code fragments that are not complete programs.
The translation of the HLASM390 source language into an intermediate tertiary language ensures the logical equivalence between the source and target languages. This sophisticated tertiary language, which is common to our entire family of translators, allows complex mapping from source language to the target. The tertiary language is automatically converted to "C" while maintaining the logical equivalence between the output "C" program and the input HLASM390program.
The "C" output file will be generated in
- Compact and portable K&R C
- Standard ANSI C code
as selected by a command line option.
