generating variable with logical operators

Dear Statlisters

I have data on ownership of household assets. I want to generate variables where logical operators '&' and '|' are used many times. Below is the sample data set and the codes that I used to create them.
I want to make sure if the codes are correct and is there any mistake? I want to create four variables, namely

1. whether a household owns "at least one asset1, asset2 or asset3"
2. whether a household owns"one asset5 OR one asset5 with one asset4"
3. whether a household owns"one asset4 BUT no asset5"
4. whether a household owns"no asset6 OR asset7 BUT at lease one asset8, asset9 or asset10"

Variables asset* indicate whether a household own specific asset or not, where 1 "yes" and 2 "no".
Variables q_* indicate how many of that specific asset household owns.

Code:

 
clear

input float hhid int asset1 q_asset1 asset2 q_asset2 asset3 q_asset3 asset4 q_asset4 ///
asset5 q_asset5 asset6 q_asset6 asset7 q_asset7 asset8 q_asset8 asset9 q_asset9 ///
 asset10 q_asset10

    bys hhid: replace assets1to3=1 if (q_asset1>=1 & q_asset1<.) | (q_asset2>=1 & q_asset2<.) ///
    | (q_asset3>=1 & q_asset3<.)
    label var assets1to3 "at least one asset1, asset2 or asset3"
    
    gen asset4to5=0
    bys hhid: replace asset4to5=1 if q_asset5==1 | (q_asset5==1 & q_asset4==1)
    label var asset4to5 "one asset5 or one asset5 with one asset4"
    
    gen noasset5=0
    by hhid: replace noasset5=1 if (q_asset4==1 & asset5==2)
    label var noasset5 "one asset4 but no asset5"
    
    gen asset6to10=0
    by hhid: replace asset6to10=1 if (asset6==2 | asset7==2) & (q_asset8>=1 & q_asset8<.) | ///
    (q_asset9>=1 & q_asset9<.) | (q_asset10>=1 & q_asset10<.)
    label var asset6to10 "no asset6 or asset7 but at lease one asset8, asset9 or asset10"

Thanks
