Local scope parameter for dow / dou ( perhaps for-each)

I don't expect that RPG will support lambda functions, nor iterators, however it will be easy for users to implement this kind of functionality if a local scopeed loop parameter could be provided by RPG to a user procedure. This will provide a bet...

heredoc syntax for large literals

When developing SQLRPG programs, I frequently have to deal with large multiline literal strings for defining SQL statements. I have in fact exceeded the size limit of a string literal in the past. It would be nice to have a HEREDOC syntax for assi...

Enable Retrieval of SQL constraint violation error information in RPG program

Allow 3rd parameter of %subst() to exceed length of string

Currently, if I use something like this: DNKYWD = %subst(NARR: 1: 10); when NARR is defined in the procedure interface like this: NARR Varchar(32740) const options(*varsize); I don't know how long NARR really is unless I check it. This causes an i...

Variadic procedures in RPG

In RPG you can make prototypes for procedures where parameter can be omitted, however the datatype and an absolute number of parameters is required in the prototype. For a more polymorphic approach I will suggest to implement variadic procedures w...

Allow array index to start from zero instead of 1

I would like to have the possibility to specify that the index of an array starts from zero instead of 1. Many times I have to code something like thiseval myArray(x+1) = 1234where x can have the value zero. If it was possible to specify that the ...
