EVAL numericField = %dec(%date(alphaDate:*MDY/):*MDY)
The parm following the char field must be the format of the char field (I used *MDY with “/”for an example).
The parm at the end of the expression must be the format of the numeric field.
So this example converts 11/22/2008 to 11222008.
If you want 2008-11-22 converted to 20081122 make both parms *ISO.
Give an example of what you want and we can be more specific.
