Sub function Excel VBA

Question

Why would this be a syntax error? it is asking for an = sign

cyberlinkcompute("A1","B2")

---

private sub cyberlinkcompute ( a as string, b as string)

end sub

isnt a sub function something that does not need an =? thanks in advance

Answer 1

删除括号或在过程名称前添加“呼叫”一词

Answer 2

Its the function-like parentheses it dislikes so either;

cyberlinkcompute "A1","B2"

or less advisably:

call cyberlinkcompute("A1","B2")
