How to access variables of one procedure function to other procedure function

Sathvik44

Hello,

I have been trying to access the y and z variables from the pointDone to getPoints and am stuck.

How can I access the y and z variables from point done to getpoints?

procedure(pointDone( w done pts )
if( done then
l=pts
x=car(l)
y=car(x)+0.0
z=car(cdr(x))+0.0
printf("Point entered was %L.\n" pts)
else
println("Point entry aborted.")
)
list(y z)
)

enterPoint( ?prompts
list( "Enter a point.")
?doneProc "pointDone"
)

procedure(getPoints()
printf("%f" ?)
)

  • Hi Sathvik,

    This cannot be done in classic SKILL but is achievable in SKILL++

    Below is an example of what your code could look like

    Cheers

    inScheme(

    ;; Let defining shared variable amongst contained procedures
    let( (x y z)

    globalProc(pointDone( w done pts )
     if( done then
     l=pts
     x=car(l)
     y=car(x)+0.0
     z=car(cdr(x))+0.0
     printf("Point entered was %L.\n" pts)
     else
     println("Point entry aborted.")
     )
     list(y z)
    )

    enterPoint( ?prompts
     list( "Enter a point.")
     ?doneProc "pointDone"
    )

    globalProc(getPoints()

     ;; Here x, y and z variables are the same as `pointDone' ones
     printf("%f" ?)
    )

    ));inScheme
