display a graphical user interface (GUI) in response to user input requesting configuration of the variable, wherein the variable is comprised in the plurality of graphical programs;

receive user input to the GUI configuring attributes of the variable, wherein the attributes comprise one or more of:

name;

data type; or

scope;

store the configured attributes; and

update the variable in each of the plurality of graphical programs in accordance with the configured attributes, thereby configuring the variable.

2. The non-transitory computer-readable memory medium of claim 1 , wherein the scope comprises one of:

local;

global; or

network.

3. The non-transitory computer-readable memory medium of claim 1 , wherein the program instructions are further executable to:

include the variable in the plurality of graphical programs in response to user input selecting the representation of the variable.

4. The non-transitory computer-readable memory medium of claim 3 , wherein at least one of the plurality of graphical programs is incompatible with the configured variable, wherein the program instructions are further executable to:

indicate an error condition for the at least one of the plurality of graphical programs.

5. The non-transitory computer-readable memory medium of claim 4 , wherein to indicate an error condition for the at least one of the plurality of graphical programs, the program instructions are executable to:

provide information relating to one or more portions of the at least one of the graphical programs that are incompatible with the configured variable.

6. The non-transitory computer-readable memory medium of claim 5 , wherein the program instructions are further executable to:

modify the at least one of the plurality of graphical programs in response to user input, wherein the modified at least one graphical program is compatible with the configured variable.

7. The non-transitory computer-readable memory medium of claim 3 , wherein to include the variable in the plurality of graphical programs, the program instructions are executable to:

create a plurality of variable references in the plurality of graphical programs, wherein the variable is deployed at a memory location, and wherein the plurality of variable references in the plurality of graphical programs operate to access the memory location.

8. The non-transitory computer-readable memory medium of claim 3 , wherein to include the variable in the plurality of graphical programs, the program instructions are executable to:

modify the plurality of graphical programs to access the variable based on respective target platforms of the plurality of graphical programs.

9. The non-transitory computer-readable memory medium of claim 1 , wherein the program instructions are further executable to:

display locations where the variable is deployed.

10. The non-transitory computer-readable memory medium of claim 9 , wherein to display locations where the variable is deployed, the program instructions are executable to:

display the variable in one or more resource trees.

11. The non-transitory computer-readable memory medium of claim 1 , wherein prior to said configuring attributes of the variable, the variable has a default configuration of the attributes of the variable.

12. The non-transitory computer-readable memory medium of claim 1 , wherein the plurality of graphical programs are comprised on a plurality of devices coupled via a network.

13. A method for configuring a variable for use in a plurality of graphical programs, wherein each of the plurality of graphical programs comprises a plurality of interconnected nodes that visually indicate functionality of the graphical program, and the method comprising:

utilizing a computer to perform:

displaying a representation of a variable, wherein the representation of the variable comprises an icon, wherein the variable is selectable via the representation for inclusion in the plurality of graphical programs, wherein the variable comprises a specification of a named memory location for storing one or more values, and wherein the variable does not store or reference program instructions;

displaying a graphical user interface (GUI) in response to user input requesting configuration of the variable, wherein the variable is comprised in the plurality of graphical programs;

receiving user input to the GUI configuring attributes of the variable, wherein the attributes comprise one or more of:

name;

data type; or

scope;

storing the configured attributes; and

updating the variable in each of the plurality of graphical programs in accordance with the configured attributes.

14. The method of claim 13 , the method further comprising:

utilizing the computer to perform:

including the variable in the plurality of graphical programs in response to user input.

15. The method of claim 14 , wherein said including the variable in the plurality of graphical programs comprises:

creating a plurality of variable references in the plurality of graphical programs, wherein the variable is deployed at a memory location, and wherein the plurality of variable references in the plurality of graphical programs operate to access the memory location.

16. The method of claim 13 , further comprising: utilizing the computer to perform:

displaying locations where the variable is deployed.

17. A system for configuring a variable for use in a plurality of graphical programs, wherein each of the plurality of graphical programs comprises a plurality of interconnected nodes that visually indicate functionality of the graphical program, the system comprising:

a processor;

a memory medium coupled to the processor; and

a display device coupled to the processor and the memory medium;

wherein the memory medium stores program instructions which are executable by the processor to:

display a representation of a variable, wherein the representation of the variable comprises an icon, wherein the variable is selectable via the representation for inclusion in the plurality of graphical programs, wherein the variable comprises a specification of a named memory location for storing one or more values, and wherein the variable does not store or reference program instructions;

display a graphical user interface (GUI) in response to user input requesting configuration of the variable, wherein the variable is comprised in the plurality of graphical programs;

receive user input to the GUI configuring attributes of the variable, wherein the attributes comprise one or more of:

name;

data type; or

scope;

store the configured attributes; and

update the variable in each of the plurality of graphical programs in accordance with the configured attributes.
