Store In Array List Of Numbers Within Same Cell

I have in column B, cells that have any number, one number or several like B2.

#
A
B
C
D
E

[Code]...

Thinking that I have a loop for rows 1 to 3:

When in column "A" is "No", I want to consider values in C and D to get:

Code:

a[1]=Cells(1,"C") & "-" & Cells(1,"D") & "-" & "ABC"

But when in column "A" is "Yes", I want to store in array each value within cell in B (in this example B2) to apply later a For/For Each
over each number (in this example are 3 values only within cell B2), something like:

Code:
a[1]=Value_In_B2[1] & "-" & "ABC"
a[2]=Value_In_B2[2] & "-" & "ABC"
a[3]=Value_In_B2[3] & "-" & "ABC"
