\h'-11u'The underscore is treated as a letter when the \-u option is turned
|
|
on (see also section 5.2). This is implemented to be compatible with
|
|
Pascal-VU and can be used in identifiers to increase readability.

|

\h'-12u'The directive \fIextern\fR can be used in a procedure-declaration or
|
|
function-declaration to specify that the procedure-block or function-block
|
|
corresponding to that declaration is external to the program-block. This can
|
|
be used in conjunction with library routines.

\h'-1u'A conformant array parameter can be passed as value conformant array
|
|
parameter without the restrictions imposed by the standard. The compiler
|
|
gives a warning. This is implemented to keep the parameter mechanism orthogonal (see also Chapter 4).

\h'-16u'If the value of the argument \fITotalWidth\fR of the required
|
|
procedure \fIwrite\fR is zero or negative, no characters are written for
|
|
character, string or boolean type arguments. If the value of the argument
|
|
\fIFracDigits\fR of the required procedure \fIwrite\fR is zero or negative,
|
|
the fraction and '.' character are suppressed for fixed-point arguments.
