<LI>True; one can be local to one procedure and one local to another. You can also have a local variable that has the same name as a global 
variable. The local variable will be the active variable inside its procedure.

<BR>

<LI>The values in local variables go away when the procedure ends.

<BR>

<LI>The sending procedure

<BR>

<LI>The receiving procedure

<BR>

<LI>False

<BR>

<LI>The 
variables that you pass are local to the calling function so the receiving function needs to know the data types of the arguments received.

<BR>

<LI>False

<BR>

<LI>False; you can pass several arguments to a function procedure but return only one value.


<BR>

<LI>Two

<BR>

<LI>Passed data may be changed by the receiving procedure and those changes remain in effect when the sending procedure regains control.

<BR>

<LI>Passed data cannot be changed by the receiving procedure except within the boundaries 
of the receiving procedure.

<BR>

<LI>Use the ByVal keyword or enclose passed arguments in parentheses.

<BR>Global Const 
NMONTHS = 12

<BR>

<LI>A. You must initialize a constant and constants cannot have  data type declarations.

<BR>B. Constants cannot have data type declarations.

<BR>C. Always define constants using the Const keyword.

<BR>D. You cannot initialize a 
global variable at the time that  you define the variable.

<BR>

<LI>Merle should never code the subscript value inside a receiving array's parentheses. Leave the parentheses blank and use the UBoumd() function inside the procedure to find the highest 
subscript in the array.

first because more is affected by the drive list box change than by changes made to the other file controls.

<LI>The directory and the filename list box controls.
