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

The example given, which has a *MDY as input, doesn't seem to match the question, but I think we all get the idea.  My issue with it is that date conversions are much more expensive than the simple data structure with numeric EVALs provided by the OP.  The other caveat is that the date operations would need a MONITOR if there's any chance of there being a bad date in the input.  For converting between formats, the date conversion version is solid and easily understood, but for just truncating off the century, I'd be inclined to go with the cheaper arithmetic method.  Just my opinion, of course.

I am getting that these are dates:
8,0 is a ccyymmdd
6,0 is a yymmdd

// mmddyy to yymmdd 
@numA = %dec(%char(%date(@numD:*mdy):*ymd0):6:0);

Converts numeric ccyymmdd to numeric yymmdd
