if INFLUENZA_1<>"" then INFLUENZA_1+" " else "" endif
I saw this statement in immunization history.
What does one empty space concatenated to INFLUENZA_1 in INFLUENZA_1+" " mean?

I'm thinking it's just formatting for output so if there is a subsequent value to show the user it is readable. So if there is a value in influenza1 add the space to separate the values in case there is a value in influenza2 or whatever the next variable for output might be.

yes output does have INFLUENZA_2 and INFLUENZA_3 if that space is added.
Only INFLUENZA_1 is the output if i remove + " "
