Defining a Program
Defining a program is similar to defining a multiple-line function. The Prgm...EndPrgm
template serves as a container for the program statements.
As an example, create a program named g(x,y) that compares two arguments. Based
on the comparison, the program should show the text “x>y” or “x≤y” (showing the
values of x and y in the text).
