Possibility for %lookup to search more than one field of a structure.

In data structures, lookup using %lookup is fantastic. But it would be interesting to add the possibility of searching on two or more fields: structure(1).field1 = 'A'; structure(1).field2 = 123; structure(1).field..... structure(2).field1 = 'B'; ...

Add *TARGET to all RPG functions similar to *SRC in DDS

Example: %SUBST(NAME:1:1)=%UPPER(*TARGET); /* new way var. NAME is mentioned only once and %SUBST is not repeated*/ Instead of %SUBST(NAME:1:1)=%UPPER(NAME:1:1); /* var. NAME is repeated twice */ Also in mathematical statements: COUNTER=*TARGET+1 ...

Provide a CTL-OPT keyword to prohibit or issue a compiler warning when $ or @ are used in Variable or Procedure names

The use of $ and @ in variable names and procedure names in RPG IV hasn't been recommend in nearly 30 years. Yet we still see some legacy developers using those symbols for some reason. I'd like to see a compiler option or CTL-OPT keyword and eith...

Provide support for null indicators in DATA-GEN in RPG

When generating JSON documents, it is a common requirement to be able to generate data like "field": null. Unfortunately, there's no easy way to do that in DATA-GEN (same problem applies to DATA-INTO in the other direction, but I see there's alrea...

%DECH enhancement for length and decimal places

The idea is to enhance %DECH() BIF: a) allow the the use %len() and %decpos() for parameters 2 and 3 Example: dcl-s n1 zoned(10:2) inz; n1 = %dech( 12345 / 1000 : %len(n1) : %decpos(n1) ); b) make parameters 2 and 3 optional and retrieve the lengt...

DATA-INTO Parser can access Populating Data Structure's Field attribute details

This would allow the parser to make better decisions in many cases. For example, Example 1: If we need the add some custom logic like if a data is getting truncated. If parser have access to know the populating field attribute it will be possible ...

Use 'IN' operator on %split to compare like in %list

When working with a list represented in a string, with %split, the 'IN' operator cannot be used as it can with the function %list. However, it is necessary to have this functionality in order to check if certain elements are present in a string li...

Standardization Currently if I need to loop untill end of file' I would do as follows. SETLL file1;DOU %EOF(file1); read file1; if %EOF(file1); LEAVE ENDIF; exsr SR01; ENDDO %EOF appears twice which is not perfect code. I could repalce the first l...

Replicate on RPGLE the cobol 88 Level

The 88 level number is not used to declare a variable, but it is used to provide a descriptive name for a condition, used to improve the readability of COBOL programs. In RPG can be coded e.g. as dcl-s flag char(1); dcl-s flag_on referer(flag) val...
