Implemented Grammar:
- prog ::= PROGRAM pid ’;’ body ’.’
- body ::= [dclpart] compstmt
- dclpart ::= VAR dcls
- dcls ::= dcl {dcl}
- dcl ::= idlist ’:’ type ’;’
- idlist ::= id {’,’ id}
- type ::= stdtype | arraytype
- stdtype ::= INTEGER | REAL | CHAR | STRING
- arraytype ::= ARRAY ’[’ intnum ’..’ intnum ’]’ OF stdtype
- compstmt ::= BEGIN stmts END
- stmts ::= stmt {’;’ stmt} ’;’
- stmt ::= ifstmt | whilestmt | assignstmt | compstmt | readstmt | writestmt | writelnstmt
- ifstmt ::= IF expr THEN stmts [ELSE stmts] ENDIF
- whilestmt ::= WHILE expr DO stmts ENDWHILE
- assignstmt ::= vbl ’:=’ expr
- readstmt ::= READ ’(’ vblist ’)’
- writestmt ::= WRITE ’(’ exprlist ’)’
- writelnstmt ::= WRITELN ’(’ [exprlist] ’)’
- vblist ::= vbl {’,’ vbl}
- vbl ::= id [’[’ expr ’]’]
- exprlist ::= expr {’,’ expr}
- expr ::= simexp [relop expr]
- simexp ::= [unary] term {addop term}
- term ::= factor {mulop factor}
- factor ::= vbl | num | ’(’ expr ’)’ | ”’.”’
- id ::= letter {letter | digit}
- pid ::= letter {letter | digit}
