Notes: 

1. A terminal symbol (literal) is always enl Insed in quotation marks (""); if a " itself is enclosed, it is written twice. Thus in the P,,,.:al EBNF below "["and '']'' represent left and right brackets in a Pascal program, wh .' reas [ and] are meta-symbols in an EBNF expression that specify zero or one occun I'nce of whatever they enclose. 

2. Every syntax has a start symbol, a met· identifier from which all the sentences in the language are generated and which is 11111 used in any EBNF expression. The start symbol for the Pascal syntax is Program. 

3. Several meta-identifiers are "orphans" ,~.g. SignedNumber) that are used in EBNF and do not appear in this Appendix.
