Some help interpreting this jass function?

[negativeone]

So.. here it is:
function E1 takes nothing returns nothing
set Fx[(1+GetPlayerId(GetTriggerPlayer()))]=ex[(1+GetPlayerId(GetTriggerPlayer()))]
if(r1())then
set gx[(1+GetPlayerId(GetTriggerPlayer()))]=l[(1+GetPlayerId(GetTriggerPlayer()))]
else
set gx[(1+GetPlayerId(GetTriggerPlayer()))]=z
endif
set Bx=StringCase(SubStringBJ(rx[(1+GetPlayerId(GetTriggerPlayer()))],1,1),true)
set cx=StringCase(SubStringBJ(rx[(1+GetPlayerId(GetTriggerPlayer()))],2,2),true)
set Qx=StringCase(SubStringBJ(rx[(1+GetPlayerId(GetTriggerPlayer()))],3,3),true)
call ClearTextMessagesBJ(UX(GetTriggerPlayer()))
if(i1())then
set Sx=Fx[(1+GetPlayerId(GetTriggerPlayer()))]
set Dx[(1+GetPlayerId(GetTriggerPlayer()))]=0
set Cx[(1+GetPlayerId(GetTriggerPlayer()))]=0
set fx[(1+GetPlayerId(GetTriggerPlayer()))]=0
set sx[(1+GetPlayerId(GetTriggerPlayer()))]=Sx
endif
if(a1())then
set Sx=Fx[(1+GetPlayerId(GetTriggerPlayer()))]
set Dx[(1+GetPlayerId(GetTriggerPlayer()))]=0
set Cx[(1+GetPlayerId(GetTriggerPlayer()))]=0
set fx[(1+GetPlayerId(GetTriggerPlayer()))]=(Sx/ 10)
set Sx=(Sx-(fx[(1+GetPlayerId(GetTriggerPlayer()))]*10))
set sx[(1+GetPlayerId(GetTriggerPlayer()))]=Sx
endif
if(n1())then
set Sx=Fx[(1+GetPlayerId(GetTriggerPlayer()))]
set Dx[(1+GetPlayerId(GetTriggerPlayer()))]=0
set Cx[(1+GetPlayerId(GetTriggerPlayer()))]=(Sx/ 'd')
set Sx=(Sx-(Cx[(1+GetPlayerId(GetTriggerPlayer()))]*'d'))
set fx[(1+GetPlayerId(GetTriggerPlayer()))]=(Sx/ 10)
set Sx=(Sx-(fx[(1+GetPlayerId(GetTriggerPlayer()))]*10))
set sx[(1+GetPlayerId(GetTriggerPlayer()))]=Sx
endif
if(V1())then
set Sx=Fx[(1+GetPlayerId(GetTriggerPlayer()))]
set Dx[(1+GetPlayerId(GetTriggerPlayer()))]=(Sx/ 1000)
set Sx=(Sx-(Dx[(1+GetPlayerId(GetTriggerPlayer()))]*1000))
set Cx[(1+GetPlayerId(GetTriggerPlayer()))]=(Sx/ 'd')
set Sx=(Sx-(Cx[(1+GetPlayerId(GetTriggerPlayer()))]*'d'))
set fx[(1+GetPlayerId(GetTriggerPlayer()))]=(Sx/ 10)
set Sx=(Sx-(fx[(1+GetPlayerId(GetTriggerPlayer()))]*10))
set sx[(1+GetPlayerId(GetTriggerPlayer()))]=Sx
endif
set ux=0
set ux=(ux+Dx[(1+GetPlayerId(GetTriggerPlayer()))])
set ux=(ux+(Cx[(1+GetPlayerId(GetTriggerPlayer()))]/ 2))
set ux=(ux+(fx[(1+GetPlayerId(GetTriggerPlayer()))]/ 3))
set ux=(ux+(gx[(1+GetPlayerId(GetTriggerPlayer()))]/ 2))
set Gx=""
set Gx=(Gx+Ax[fx[(1+GetPlayerId(GetTriggerPlayer()))]])
set Gx=(Gx+Tx[gx[(1+GetPlayerId(GetTriggerPlayer()))]])
set Gx=(Gx+cx)
set Gx=(Gx+"-")
set Gx=(Gx+Qx)
set Gx=(Gx+Nx[Cx[(1+GetPlayerId(GetTriggerPlayer()))]])
set Gx=(Gx+Bx)
set Gx=(Gx+qx[sx[(1+GetPlayerId(GetTriggerPlayer()))]])
set Gx=(Gx+"-")
set Gx=(Gx+bx[Dx[(1+GetPlayerId(GetTriggerPlayer()))]])
set Gx=(Gx+tx[ux])
call DisplayTimedTextToForce(UX(GetTriggerPlayer()),240 .,Gx)
call DisplayTimedTextToForce(UX(GetTriggerPlayer()),240 .," ")
call DisplayTimedTextToForce(UX(GetTriggerPlayer()),240 .," ")
call DisplayTimedTextToForce(UX(GetTriggerPlayer()),240 .," ")
call DisplayTimedTextToForce(UX(GetTriggerPlayer()),240 .," ")
endfunction


It's supposed to give you a save-code for a map.
this is my first time looking at jass, so i dunno what any of the functions in here do like "getplayerId" and GetTriggerPlayer..

if someone could clarify for me what this thing does I'd appreciate it

I'd have to see the entire war3map.j to be able to make a 100% guess to it because that isn't a complete source.
