EBNF or BNF for the LOGO programming language

由 只愿长相守 提交于 2019-12-20 12:23:47
问题 Does anyone know where I can get the BNF or EBNF for the LOGO programming language? 回答1: A BNF grammar might not be too useful in certain circumstances... Writing a LOGO that's accurately compatible with existing/historical implementation isn't an easy task (I worked on such a project). The problem is that the parser doesn't do the full job, and the evaluator (interpreter) has to work with partial data. Consider this example: proc1 a b proc2 c It could mean proc1(a, b, proc2(c)) or proc1(a, b

问题 I am currently writing a Logo to Postscript compiler. My PS output code doesn't seem to be valid. Any ideas what could be the problem? Or what the actual PostScript version for the LOGO should look like? The LOGO input code PROC LDRAGON ( LEVEL ) IF LEVEL == 0 THEN FORWARD 5 ELSE LDRAGON ( LEVEL - 1 ) LEFT 90 RDRAGON ( LEVEL - 1 ) ENDIF PROC RDRAGON ( LEVEL ) IF LEVEL == 0 THEN FORWARD 5 ELSE LDRAGON ( LEVEL - 1 ) RIGHT 90 RDRAGON ( LEVEL - 1 ) ENDIF PROC MAIN (VOID) LDRAGON ( 11 ) The code

The "joke" question Joel asked during podcast #58 made me all nostalgic for Logo, which was the second language I ever programmed in, after Basic, and which is why I never had any trouble with recursion in college. Are there any implementations of Logo for Windows or Linux (the platforms I can use) or Mac (because I know I'm not alone in this world)? How can I get the Logo programming language for my computer? I'm teaching my kids LOGO successfully on Windows using Elica LOGO . (Kids ages are presently 12 and 10.) The package's strengths include many "advanced" extensions, beyond the basic 2
