is this assigning values 0 or 1 to a table?

As VB code (see snippet)

Note: your SQL would be easier to understand if you used aliases for your tables.
If T_FPtr_GeneralSearch].[PromoPeriod] = "Period" Then
   Value = 1
 
ElseIf T_FPtr_GeneralSearch].[PromoPeriod] = T_100_q010_PromoTitleandDetailsAsOne_SELECT].[T_OUTPUT_PromoChosenAtEntry_MAIN].[promo_period] Then
   Value = 1

it's either 0 or 1 based on the current  value of

T_FPtr_GeneralSearch].[PromoPeriod]

T_FPtr_GeneralSearch].[PromoPeriod]
and [T_100_q010_PromoTitleandDetailsAsOne_SELECT].[T_OUTPUT_PromoChosenAtEntry_MAIN].[promo_period]

if T_FPtr_GeneralSearch].[PromoPeriod] = "Period' or
T_FPtr_GeneralSearch].[PromoPeriod] = [T_100_q010_PromoTitleandDetailsAsOne_SELECT].[T_OUTPUT_PromoChosenAtEntry_MAIN].[promo_period], then the value of the statement is 1,
0 otherwise

since you haven't shown us the entire SQL statement and the code that invokes the SQL, we don't know.

I asked to see the SQL, not a screen shot of the query builder.  

Also, what about the code that invokes it?  If you need to know HOW the 0/1 value is used, it can only be answered by examining the invoking/consuming routines.  For all I know, these values might be bound to a checkbox control somewhere.

Within the Where clause, the 0 and 1 values are used as a replacement for a Boolean OR operator.  The Where clause should be written as shown in the snippet.
