Calling an Internal Subroutine
To define an internal subroutine, use the
Define command with Prgm...EndPrgm.
Because a subroutine must be defined before it can be called, it is a good practice to
define subroutines at the beginning of the main program.
:subtest1()
:Prgm
:For i,1,4,1
: subtest2(i,iù1000)
:EndFor
:EndPrgm
:subtest2(x,y)

: Disp x,y
:EndPrgm
