All you need to know is
1. How to initialize an array:
Dim Array(10) As Integer
For i = 1 to 10
Array(i) = 0
Next i

2. Declaration of variables:
Dim VariableName As DataType

3. Using loops:
While CONDITION 'Checks Condition at the Beginning
...
EndWhile

REPEAT
...
UNTIL Condition 'Check Condition at the End and does the code at least once

4. Structures:
STRUCTURE StructureName
DIM Var1 AS DataType
...
DIM VarX AS DataType
END STRUCTURE

4. Procedures & Functions:
PROCEDURE Name
Instructions
END PROCEDURE

FUNCTION Name
Instructions
END FUNCTION

6. Pseudocode
Write in simple and Understandable words like a story of events.

READ FILE
UNTIL NOT EOF, DO
INSTRUCTIONS
LOOP

*EOF = End Of File

Code: 
Public Function algol(x As String)
Dim hr As String
Dim min As String
Dim proxx As String
 
 
total = x
hr = Left(total, 2)
 
min = Right(total, 2)
 
 
proxx = ((Val(hr * 2) + (Val(min / 30) + 1)))
 
End Function
 
'To call the function
Private Sub Command2_Click()
algol ("20:30")
End Sub

Thank you so much but the reply was a bit late and I already come to a similar answer.

Still THANK YOU.

By the way guys how was the paper 22/21/23 ?

Guys I think the GT for paper 22 will be low than in MJ 2011 because it was hard compared to all the 2011 p22's...

Actually, this code:
Code: 
proxx = ((Val(hr * 2) + (Val(min / 30) + 1)))
Should be:
Code: 
proxx = ((Val(hr * 2) + (Val(min DIV 30) + 1)))
DIV is different from /

How did you guys do?
I found it very easy with all the programming.
