TechTalk: SDA Field Name Restriction

General
Typography
  • Smaller Small Medium Big Bigger
  • Default Helvetica Segoe Georgia Times

When you create or modify display file source code (using either SEU or SDA), do not use the field name FLD000 if you ever want to use SDA to modify the code. If you use the field name FLD000, a serious error will occur in SDA, and you will get the Dump SDA Work Spaces screen.

SDA generates field names FLD001 through FLD999 and stores the numeric portion as a subscript value in an array. The field FLD000 causes escape message MCH0603 (Range of subscript value or character string error) because the subscript value is less than the lower boundary of the array.

A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
