what does the symbol ^ mean?

[Pooja98]

hi experts,

i came across the type of merging, can't understand this part alone.....i'll post the whole code and i'll highlight my doubt in  bold letters

For Example,

data three;

merge two (in=A)

one (in=B);

by ID;

if A;

if ^B then do;

Name=Student_Name;

Marks= Total_Mark;

end;

run;

what does the ^ symbol stands for?

TIA

Hi @Pooja98,

It's the Boolean operator "NOT", so you can write equivalently

if not B then do;

In your example the condition means "the ID value does not occur in dataset ONE."
