Re: Example of right justifying a character field.

I suspect that SQL is not as efficient - here is what the SET statement does, according to the manual -

"The SET variable statement produces a result table consisting of at most one row and assigns the values in that row to variables."

Besides that, there are 2 or 3 inline function calls.

There's a really simple way to do this in RPG.

EVALR.

Simply code EvalR result = shortField;

Or if shortField has trailing spaces then:

EvalR result = %TrimR(shortField);

I cannot agree with Jonathan about using SQL for tasks like this - SQL is great for what it is designed for. Replacing a perfectly good built-in language feature is not what it was designed for. If you need to right adjust _within_ and SQL operation sure but ...

Just my 10 cents worth.

I tend to do all of this kind of activity in SQL whenever possible.

dcl-s char_15 char(15);
dcl-s char_30 char(30);
dcl-s char_7 char(7) inz('STUFF'); // char_7 = 'STUFF '

exec sql
set :char_15 = lpad(rtrim(:char_7), length(:char_15)); // char_15 = ' STUFF'

exec sql
set :char_30 = hex(:char_15); // char_30 = '40404040404040404040E2E3E4C6C6'

In find SQL built-in functions intuitively easier to understand and simpler to use than equivalent RPGLE BIFs, and there aren't always equivalents.

I would not like to use a do loop to do this.
