Addition across variable using array statement

[UcheOkoro]

Please, I need help adding across variables using the array statement. I have 73 variables with names Pscy1-Psych73. These are binary(1,0) categorical variables. I need to create a variable which is the sum of the 73 variables.

Thank you

No array needed.

total = sum(of psych1-psych73);
