I am working on a pseudocode with call procedures that allows a customer to select their gasoline service and then their gasoline grade. The pseudocode should calculate their charges and display them for the customer. I have a main module and 3 sub modules (Input, calculate and output). The user defines their service type and gasgrade in the input module. Apparently, the gasgrade value doesn't retain in the calculate or output modules. I would redefine the variable in these two submodules, but the user defines the value of gasgrade, so I can't define it because I don't know what the customer will choose.

Can anyone tell me how to make the variable definition stick throughout all the modules?

Try passing the variables you want the program to remember outside the procedure as a reference instead of a value.
