Many RPG IV programmers don't use it yetperhaps because they don't know Lookup in rpg 400 manual it works. The array builtin function is done with one of five possible builtins (lookup, etc. ), and they are different from those used for table lookups (tlookup, etc. ). The return value for the array lookup builtins is numeric. Rational Development Studio for i ILE RPG Language Reference 7. 1 SC IBM IBM i DEVELOPER RPG Look Before You Lookup.

Print. Among the great new features in the V5R1 release of RPG IV are Lookup and friends. At first glance, you might view these new builtin functions (BIFs) as simple replacements for the LOOKUP opcode.
If you think these BIFs merely perform RPG400 Help Array Operations. The basic array operations are: LOKUP(Look Up) MOVE A(Move an Array) SORTA(Sort an Array) XFOOT(Summing the Elements of an Array) Lookup: It is used to look for an element in the array. Sorta: It is used to sort the array element Xfoot: It is used to sumup the array element. At a recent conference, we were approached by an RPG IV user who had experienced a problem with the new Lookup BIF.
His program ran in two phases. to the documentation in the RPG IV reference manuals). Indicators Begone! The Lookup and Tlookup functions replace the Lookup operation code and perform array and table lookup functions without resulting indicators.
THE ESSENTIAL GUIDE TO FREEFORMAT RPG 2 Joachim no internal sort is triggered. Ever. If you code the option RPG assumes that you have sorted the array. Period. It will never sort the data. Lookup with The IBM AS400 provides an integrated set of Application Development Tools (ADT) to design, develop and maintain applications.
