type and end type

[Jamie]

Hi guys - I was recently exposed to PowerBuilder and was told to familiarize myself with it. I am currently reading through some Powerscripts. As much as I understand most of it - there are some which I am not getting. So I am asking here in hopes of getting some answers.

Note: As I am not sure what is the commenting convention in Powerscript I have used what I have been using for other languages. In those comments is my understanding of the code, do correct me if I am wrong.

/***
Declaring within this forward statement -
it is something like a function prototype
***/
forward
/***
Declaring a global variable type - game_code - from the
game_template
***/
global type game_code from game_template
end type

/***
Declaring a local variable type - unocard_1 -
from the uno_template that is within game_code
***/
type unocard_1 from uno_template within game_code
end type
end forward


/***
After the 'prototype' we create the actual variable here
with properties in place
***/
global type game_code from game_template
long backcolor = 12632256
unocard_1 unocard_1
end type


global game_code game_code


type unocard_1 from game_template`unocard_1 within game_code
end type


Thanks.
