Re: [EpiData-list] cannot read local sign in EpiData Entry classic 3.1 (if formulation)

epidata-list@lists.umanitoba.ca suggestion to "try this":

FIELD1 BEFORE ENTRY IF (oeoe="湖") THEN GOTO FIELD2 ENDIF END END‍

---

---

is a very good general advice in all situations where we apply if .

The suggestion was to change: from: IF oeoe="湖" THEN to : IF (oeoe="湖") THEN

This is also relevant for analysis. Good practice is therefore in all situations with "if" regardless of software:

do not write like this: if v1 = 1 or v2 = 2 then v3 = 2 which is "unsafe" practice in comparison to:

if (v1 = 1) or (v2 = 2) then v3 = 2

or even further enclosing in parenthesis:

if ((v1 = 1) or (v2 = 2)) then v3 = 2
