How can I have TWO separate Global Variables with the SAME Name?

[bobkrohn]

OK, here's my learning experience.
Del, Shift Del and Shift Esc didn't do anything.

I didn't realize that Exporting a Variable in a program that has been compiled created a permanent variable.
The way to "delete" the variable is to simply remove the Export instruction from the program.
I had two related programs that did the Export command for "SF".
However, I assumed that they would be referring to the same variable.
i.e. could access the value held there. OOPS!
There is no way to know which variable was which.

I have a better understanding now. Thanks
