Logical constants are typed as
FALSE. Note that they
are not delimited by decimal points as in FORTRAN.
String constants consist of any sequence of characters enclosed in either single or double quotes. Two consecutive quote symbols in a string are used to represent a single quote. String constants are the one place in ICL where the case of letters is significant.
Some examples of constants:
Real 1.234E-5 3.14159 Integer 123 %B100110 %O377 %Xffff Logical TRUE FALSE String 'This is a string' "So is this" ''
