Where is this in the SAS documentation?

[deleted_user]

Does anyone know where this is documented?

Data data2 ;
Set data1 ;
If var1 eq :’text’ ;
Run ;

What does the ‘:’ before the text string do that causes it to look for the text string ‘text’ in the variable?

Thanks.

It's under "Comparison Operators" in base SAS
