2111	 Spelling Correction in Systems Programs	 Several specialized techniques are shown for efficiently incorporating spelling correction algorithms in to compilers and operating systems. These include the use of syntax and semantics information the organization of restricted keyword and symbol tables and the consideration of a limited class of spelling errors. Sample coding for performing spelling correction is presented. By using systems which perform spelling correction the number of debugging runs per program has been decreased saving both programmer and machine time. spelling correction error correction debugging compilers operating systems diagnostics error detection misspelling lexical analysis systems programming
