Re: Want to replace MOVE numeric 8 to numeric 6 in free form

In terms of efficiency your idea is about as good a performer as you are going to get. Only thing I can think of that would be a bit faster would be to prototype the appropriate MI function. But I haven't got time to do that right now.

For sure no matter what approach you use you should bury it in a subprocedure so that anyone coming after you knows what is happening without needing to understand the mechanics.

I've a zoned 8,0 that is being MOVEd to a packed 6,0. I want to convert

I can think of putting the zoned 8,0 into a data structure with a zoned
6,0 overlaying the last 6 positions, then use an assignment statement.

In the following, I wanted to use CNVDAT instead of CNVDT8. That can
work with fields from a file, didn't work so far, so will use an
assignment of CNVDT8 = CNVDAT for now.

* Allow "MOVE" of 8-digit ot 6-digiy
D DATE8TO6 DS
D CNVDT8 8s 0
D CNVDT6 6S 0 overlay(DATE8TO6 : 3)

Then CNVDT6 should have the value I want - this is 8-digit dates to
6-digit in YMD format.

Is there a better way? I looked at several articles - Bob Cozzi, Jon
Paris, some other forums - none that I saw dealt with the MOVE from a
longer numeric to shorter.

TIA
