indicator variables in 6.5++ dos

[Bernard Lis]

I inherited a 5.5 dos system that I am trying to convert to 6.5++   It aborts at   if iv3 <> 0 then iv3 is an indicator variable in the preceding select clause. when the select clause does not find anything, iv3 is not a defined variable.   This worked in 5.5    Did 5.5 create the variable when a select clause fails?   Should 6.5++ do the same?   This technique is used throughout this program.  any suggestions on an easy way to fix the problem?   Bernie Lis, Megabytes, Inc.
