Donegan","doi":"10.1145/800218.806634","DOIUrl":"https://doi.org/10.1145/800218.806634","url":null,"abstract":"Writing a compiler for a small machine with minimal software support can be quite difficult because the program is long and debugging aids are usually inadequate. In addition, the usual techniques for compiler writing tend to produce programs which are quite large when compared to, for example, a BASIC interpreter. This frustrates efforts for producing compilers on small machines. We describe a method which can be used to reduce the size of a compiler and simultaneously provide good debugging tools. The resulting compiler sacrifices little in terms of execution speed (in part because compilers on minicomputers are often I/O bound). We have used this method to write an MPL [1] compiler for a Microdata 32/S minicomputer. The compiler requires approximately 12K bytes of memory as opposed to 32K bytes required by the compiler produced by the manufacturer, and compiles at essentially the same speed. Appendix II outlines the syntax of the MPL language and is included to illustrate the size of the language being compiled. MPL is based on PL/I and is quite similar to the PL/M* [2] language developed by the INTEL Corporation.\u0000 The method described here uses an interpretive language for writing the compiler. Thus the interpreter is the only machine language program written. We coded the interpreter in MPL and used a cross compiler to compile it, however, the interpreter could have been easily coded in assembly language. Figure 1 illustrates the savings of the interpretive language over machine code. The procedure IF_STAT is typical of a routine which might appear in a recursive descent compiler for MPL. The gain in space occurs because machine language instructions carry too much information content when applied to a special purpose (such as compiling). Note for example that a subroutine call for the Microdata requires 6 bytes, but all that is really needed is an opcode to indicate a call and a byte to indicate which of a few subroutines is to be called.","PeriodicalId":344026,"journal":{"name":"SIGMINI '78","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121975911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decision tables - an effective programming tool 决策表-一个有效的编程工具

Langenwalter","doi":"10.1145/800218.806637","DOIUrl":"https://doi.org/10.1145/800218.806637","url":null,"abstract":"The manager or owner of a small to medium size business often has strong ideas on how he wants to run his business. The “packaged” software to go with the mini computer that he can afford just doesn't give him the flexibility he wants. To keep the software costs down and still be able to get the desired programs, a programming method that gets the results at low cost is needed. Two companies reported reductions of 3 to 1, i.e. costs were down to one-third of the previous methods, by using decision tables to write the logic. With such substantial reductions in costs, the mini computer owner can have the tailored programs he wants with a reasonable investment.\u0000 A decision table processor, MUSCL, has been developed and is implemented on mini computers. This paper shows how to write and solve decision tables as implemented.\u0000 Ideally problems are solved in steps. The problem is defined clearly. Criteria or conditions are established. Then a series of actions is taken. The expression that describes the conditions and actions is a “decision rule”. A decision table is the structure for describing a set of decision rules. A decision table gives us a way of recording decision patterns so that we can make consistent decisions and see how to change the patterns to meet changing conditions.","PeriodicalId":344026,"journal":{"name":"SIGMINI '78","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128718565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was observed that the bulk of the data involved in these interactions was in the displays themselves and that certain display drivers operated on action strings similar to those in production language systems. The development of special Floyd-Evans production languages oriented toward a visual interactive environment was therefore undertaken. Based on two experimental interpreters which have been implemented, the language itself has now been substantially refined and compilers for a common language have been designed with one being implemented. In the first implementation which was accomplished on a Datapoint 2200, a substantial portion of the effort was devoted to a pedagogic display of the parsing process. In the second implementation on an Interdata 85, all of the programming was made reentrant so that multiple users can be served using the same or different target languages. Furthermore, some of the basic functions were reduced to microcode, although it was not possible to carry this as far as had been hoped. It was also learned during development of the second system that left-part matching and right-part replacement could be treated as generalized actions—thus simplifying the internal structure of the interpreter. Development of these systems is part of ongoing research with programming languages and automated programmer assistance.","PeriodicalId":344026,"journal":{"name":"SIGMINI '78","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124758792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
