I havent used JavaScript much but I was planning on using it to replicate a program I wrote in Liberty BASIC. Is it possible to "goto" a set location for example, if one variable equals another you skip a chunk of code and go on to the next bit?

I have added the Liberty BASIC code I am attempting to replicate below. It calculates the PMCC for the values entered with a maximum of ten sets of data.

[start]

input "How many sets of values do you have? "; sets

let setscount = 0

if sets = 0 then [help]

[xvalues]

input "Enter the first x value. "; xone

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xtwo

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xthree

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xfour

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xfive

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xsix

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xseven

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xeight

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xnine

let setscount = setscount + 1

if setscount = sets then [yvalues]

input "Enter the next x value. "; xten

let setscount = setscount + 1

if setscount = sets then [yvalues]

[yvalues]

let setscount = 0

input "Enter the first y value. "; yone

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; ytwo

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; ythree

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; yfour

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; yfive

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; ysix

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; yseven

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; yeight

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; ynine

let setscount = setscount + 1

if setscount = sets then [calc]

input "Enter the next y value. "; yten

let setscount = setscount + 1

if setscount = sets then [calc]

[calc]

let xbar = (xone + xtwo + xthree + xfour + xfive + xsix + xseven + xeight + xnine + xten)/sets

let ybar = (yone + ytwo + ythree + yfour + yfive + ysix + yseven + yeight + ynine + yten)/sets

let sumxy = (xone*yone)+(xtwo*ytwo)+(xthree*ythree)+(xfour*yfour)+(xfive*yfive)+(xsix*ysix)+(xseven*yseven)+(xei ght*yeight)+(xnine*ynine)+(xten*yten)

let sumx = xone + xtwo + xthree + xfour + xfive + xsix + xseven + xeight + xnine + xten

let sumy = yone + ytwo + ythree + yfour + yfive + ysix + yseven + yeight + ynine + yten

let sumxsumy = sumx*sumy

let sumxsq = (xone^2)+(xtwo^2)+(xthree^2)+(xfour^2)+(xfive^2)+(xsix^2)+(xseven^2)+(xeight^2)+(xnine^2)+(xten^2)

let sumysq = (yone^2)+(ytwo^2)+(ythree^2)+(yfour^2)+(yfive^2)+(ysix^2)+(yseven^2)+(yeight^2)+(ynine^2)+(yten^2)

let sumxallsq = sumx^2

let sumyallsq = sumy^2

let bottomxbrac = sumxallsq/sets

let bottomybrac = sumyallsq/sets

let bottomx = sumxsq-bottomxbrac

let bottomy = sumysq-bottomybrac

[answer]

let top = sumxy-(sumxsumy/sets)

let bottom = bottomx*bottomy

let rootbottom = SQR(bottom)

let pmcc = top/rootbottom

print "The PMCC of the numbers you entered is: "; pmcc

[rerun]

input "Run again? (Enter yes or no) ";rerun$

if rerun$ = "yes" then [start]

end

[help]

print "This program calculates the PMCC of the numbers entered."

print "First enter the number of x and y values you have and then"

print "enter the x and y values themselves. You must enter more than"

print "one set of data."

print "This program was made by Harry Mills for free distribution."

Sorry its long but I have only just started programming so I dont know any other way. (Could you do it with arrays maybe?)

If you know any way I can either shorten the code or neaten it up please tell me.

Thanks
