Concatenate blank space

I had a setback in concatenating blank spaces in between variables/fields.
My case scenario. I have 10 fields. Need to concatenate them all. However, lets say for field6, 7, and 8, i would like them to have spaces in between when concatenated. For the rest of the fields, no space is needed when concatenated together.

How i solved:

I declared a variable eg: v_space type C value ' '.
The space in between the apostrophes is done via pressing buttons ALT 2 5 5...and magically creates a blank space in between the apostrophes.
