The keyword CONSTANT
appears only once in the declaration section, before the data-type assignments for constants. Each data-type statement can be followed by as many identifiers of the same type as you want to define. For example:
The identifiers in the CONSTANT
statement must have their values assigned in the statement. The value can be any expression that does not contain variables or parameters.
CONSTANTtype identifier := value [, identifier := value, ...];
[ type identifier := value, ...;]
CONSTANTSTRING out_file :=’/usr/group/doc12.stm’ ;
STRING in_file := ’/usr/group/insert12.doc’;
INTEGER page_length := 66, page_width:=72;
