Restrictions |
|
list_var_dim |
List of var_dim separated by the character ','. |
None. |
|
var_dim |
Name of a variable expressed
in one of the following forms: |
None. |
|
nom_var |
nom_de_variable. |
None. |
|
list_dim |
List of exp_dim separated by the character ','. |
Number limited to 4. |
|
exp_dim |
Integer
expression representing the number of elements of the variable (from 0 to
exp_dim-1) |
The number of elements must belong to [1,65535]. If a range is given the starting index must belong to [-32768,32767]. |

Libelle is used to declare text type variables, scaling them if necessary.
If Local is used, the variables will be local to the routine or sub-programme, and deleted when the sub-programme or routine is completed.
If Extern is used, the variable is not created, but its existence and type are checked.
If Extern is not used, a declaration of a variable already existing in class [V] or [L] will cause this variable to be deleted, followed by its recreation with the dimensions and type given. After a declaration, the variable is always initialised (that is, set to 0 for a variable of type Text, for all indices of the variable).
Values for Libelle are between 0 and 255.
