The %D_FLOAT directive produces a VAX D_floating literal
regardless of the current floating point default of the
compilation. Without the directive, the format of a double
precision floating literal will be determined based on the
setting of the /FLOAT DCL qualifier or the [FLOAT] module-level
attribute. The syntax is:
%D_FLOAT floating-point-literal
49.27 – G_FLOAT
The %G_FLOAT directive produces a VAX G_floating literal
regardless of the current floating point default of the
compilation. Without the directive, the format of a double
precision floating literal will be determined based on the
setting of the /FLOAT DCL qualifier or the [FLOAT] module-level
attribute. The syntax is:
%G_FLOAT floating-point-literal
49.28 – T_FLOAT
The %T_FLOAT directive produces an IEEE T_floating literal
regardless of the current floating point default of the
compilation. Without the directive, the format of a double
precision floating literal will be determined based on the
setting of the /FLOAT DCL qualifier or the [FLOAT] module-level
attribute. The %T_FLOAT directive is not supported on OpenVMS
VAX systems. The syntax is:
%T_FLOAT floating-point-literal
50 – Comments
Comments document the actions or elements of a program. The
text of a comment can contain any ASCII character except a
nonprinting control character, such as an ESCAPE character. You
can place comments anywhere in a program that white space can
appear.
You signify a comment with braces or with a parenthesis and
asterisk pair, as follows:
Example:
{ This is a comment }
(* This is also a comment *)
VSI Pascal allows you to mix the two symbol pairs in one
comment, as follows:
{ The delimiters of this comment do not match. *)
(* VSI Pascal allows you to mix delimiters in this way. }
VSI Pascal does not allow you to nest comments. The following
example causes a compile-time error because the comment ends at
the first closing delimiter (}).
Example
The following is illegal:
(* Comments can not be nested { in VSI Pascal } within
a program *)
