run macro dependent on value in cell a1

hello,

i have a formula in cell a1 which turns into a value. this value in cell a1 is exactly the same as the name of my macro. i want to know if i can have the macro run based on the value of cell a1.
for example, i can run the following macro --- Application.Run "Num_of_Columns" with no problems. but in this new situation, i want to run something like --- Application.Run "Range("A1").Value.Select"

the reason i need this is because i have multiple macros, and the one that gets run depends on the value from cell a1.

thank you in advance.
