I tried to pass a variable to a subroutine which is inside of another subroutine and it is not sucessfull. For example:
 



[code]

temp1   VAR   Byte 

cs      VAR   Byte
 

Subroutine1   SUB  2

Subroutine2   SUB  1

 

PROGRAM Start

 

Main:

 

cs = 5

 

Subroutine1 3, cs

 

END

 

 

SUB Subroutine1
  temp1 = __PARAM1 

  cs = __PARAM2
  [b]Subroutine2 cs[/b]
  temp1 = temp1 + 1

  'Do something with temp1 now....
  ENDSUB

 


SUB Subroutine2 

  cs = __PARAM1
  cs = cs + 1

  'Do something with cs now....
  ENDSUB
[/code]
 

 


Something like this format does not work unless even if I declare in the begining of the program: cs = 5

 

However, If I change it to this, it works:

 



[code]


temp1   VAR   Byte 

cs      VAR   Byte
 

Subroutine1   SUB  1

Subroutine2   SUB  1

 

 
PROGRAM Start

 

Main:

 

Subroutine1 3

 

END

 

SUB Subroutine1
  temp1 = __PARAM1 
  [b]Subroutine2 5[/b]
  temp1 = temp1 + 1

  'Do something with temp1 now....
  ENDSUB

 


SUB Subroutine2 

  cs = __PARAM1
  cs = cs + 1

  'Do something with variable2 now....
  ENDSUB
[/code]
 Any ideas?
