proc sql question and ^= operator

[taupirho]

I have a proc sql statement and the first line of the where clause looks like

WHERE calculated BRANCH_NO ^= TABLE1.BRANCH_NO

Can anyone tell me what the ^= operator is. I'm guessing it's just equivalent to != but maybe it's some kind of logical operator

Thanks in advance

It means 'not equal to'
