Application Titles 

Application titles are literal strings that can be used on screens and
reports.  Any change to an application title is immediately reflected on
screens and reports that use the title.

Variables 

All variables have a fixed length and type.  The type of data a variable
can contain is determined by its edit code.

HP ALLBASE/4GL initializes numeric variables to zero, and alphanumeric
variables to spaces, when the application starts.  They are not
initialized at any other time.

Constants 

You can define numeric constants and alphanumeric constants.  Numeric
constants can contain numeric values and the characters - and + .

Alphanumeric constants are literal strings, and can contain any printable
characters.
