• Replace the name by another character string at the users discretion (between quotes;
this is the only occurrence where SWAN is case sensitive; e.g. for text to appear in
a plot.
Example:
command scheme: KEYword ’City’ data
command file: KEY ’Amsterdam’ data
• Copy the name of the variable (without the quotes) literally followed by an = sign
and a name at the users discretion (between quotes). SWAN interprets the copied
name in the command file as a keyword with all the characteristics of a keyword such
as ending a sequence of optional data (see below). As with other keywords the name
of the variable is case-insensitive.
Example:
command scheme: KEYword ’City’ data
command file: KEY city=’Amsterdam’ data
As a rule, an error message will result if numerical data is given where character data
should be given.
Numerical data are simple numbers , e.g. 15 or −7 (integer data), or 13.7 or 0.8E−4
(real data). Whether or not integer number or real number should be given by the user is
indicated in the description of the command scheme.
Note that a decimal point is not permitted in an integer number. On the other hand, an
integer number is accepted by SWAN where a real number should be given.
In a command scheme, the number is always indicated with a name (which is placed
between square brackets). In the command file such a name can be entered in two ways:
• Replace the name by a number (not between square brackets).
Example:
command scheme: KEYword [nnn]
command file: KEY 314
• Copy the name of the variable (without the quotes) literally followed by an = sign
and the number (not between square brackets). SWAN interprets the copied name
in the command file as a keyword with all the characteristics of a keyword such as
ending a sequence of optional data (see below). As with other keywords the name of
the variable is case-insensitive.
Example:
command scheme: KEYword [nnn]
command file: KEY nnn=314
