In order to perform a Variable Declaration it is necessary to use the DECL/ command.
With that command it is specified the variable type and its name.

The variables can be:

COMMON
GLOBAL
LOCAL

and can be declared in the following types:

BOOL
CHAR
INTGR
REAL
VECTOR
LONG


$$ Declaration of different variable types

DECL/CHAR,80,TCDIRS
DECL/INTGR,TCNSLT


$$ It is possible to declare different variables of the same type in the same row

DECL/DOUBLE,TCDIFX,TCDIFY,TCDIFZ


$$ Declaration of an array of 10 char, called result. Each char has 80 characters.

DECL/CHAR,80,RESULTS[10]


$$ Declaration of an array of 10 x 5 char

DECL/CHAR,80,RESULTS[10,5]
