A complying processor is required to provide a definition of all the implementation-defined features of the language. To facilitate the production of this definition, all the implementation-defined aspects specified in clause 6 are listed again in this annex.
E.1 6.1.7
The string-characters which denote an implementation-defined value of the required char- type.
NOTE --- For processors which compile and execute in different environments, the above may require the definition of two character sets and a mapping between the two.
E.2 6.1.9
Provision of the reference tokens , [, and ], of the alternative token @, and of the delimiting characters { and }, is implementation-defined.
E.3 6.4.2.2 b)
The values of the implementation-defined approximation to an implementation-defined subset of the real numbers denoted by signed-real.
NOTE --- The subset defined above may be by reference to another specification.
E.4 6.4.2.2 d)
The values of char-type which are an enumeration of a set of implementation-defined characters.
E.5 6.4.2.2 d)
The ordinal numbers of each value of char-type are implementation-defined.
E.6 6.4.3.5
The set of characters designated prohibited from textfiles is implementation-defined.
E.7 6.6.5.2
The point at which the file operations rewrite, put, reset, and get are actually performed is implementation-defined.
E.8 6.7.2.2
The value denoted by the constant-identifier maxint is implementation-defined.
E.9 6.7.2.2
The accuracy of the approximation of the result of the real operations and functions to the mathematical result is implementation-defined.
E.10 6.9.3.1
The default value of TotalWidth for integer-type is implementation-defined.
E.11 6.9.3.1
The default value of TotalWidth for real-type is implementation-defined.
E.12 6.9.3.1
The default value of TotalWidth for Boolean-type is implementation-defined.
E.13 6.9.3.4.1
The value of ExpDigits is implementation-defined.
E.14 6.9.3.4.1
The value of the exponent character ('e' or 'E') used on output of values of real-type is implementation-defined.
E.15 6.9.3.5
The case of each character of 'True' and 'False' used on output of values of Boolean-type is implementation-defined.
E.16 6.9.5
The effect of the procedure page when applied to a textfile which is in generation mode is implementation-defined.
E.17 6.10
The binding of a file-type program-parameter is implementation-defined.
E.18 6.10
The effect of reset and rewrite on the standard files input and output is implementation-defined.

Annex F

Implementation-dependent features
A complying processor is required to provide documentation concerning the implementation-dependent features of the language. To facilitate the production of such documentation, all the implementation-dependent aspects specified in clause 6 are listed again in this annex.
F.1 6.4.3.5
For any textfile t, the effect of attributing to a component of either t.L or t.R a member of the characters prohibited from textfiles is implementation-dependent.
F.2 6.5.3.2
The order of evaluation of the index-expressions of an indexed-variable is implementation-dependent.
F.3 6.7.1
The order of evaluation of expressions of a member-designator is implementation-dependent.
F.4 6.7.1
The order of evaluation of the member-designators of a set-constructor is implementation-dependent.
F.5 6.7.2.1
The order of evaluation of the operands of a dyadic operator is implementation-dependent.
F.6 6.7.3
The order of evaluation, accessing, and binding of the actual-parameters of a function-designator is implementation-dependent.
F.7 6.8.2.2
The order of accessing the variable and evaluating the expression of an assignment-statement is implementation-dependent.
F.8 6.8.2.3
The order of evaluation, accessing, and binding of the actual-parameters of a procedure-statement is implementation-dependent.
F.9 6.9.5
The effect of inspecting a textfile to which the page procedure was applied during generation is implementation-dependent.
F.10 6.10
The binding of non-file variables denoted by the program-parameters to entities external to the program is implementation-dependent.
