Re: Date Difference

Using RPG IV,
1. Create 2 DATE data fields
  D Date1     S          D   Datfmt(*ISO)
  D Date2     S          D   Datfmt(*ISO)

2. Load the dates with YOUR variables
  C          *MDY      Move   Your_Var_1     Date1
  C          *MDY      Move   Your_Var_2     Date2

3. Subtract Date1 from Date2 using the SUBDUR Op code
  C          Date2     SubDur Date1          Date_Diff:*D

Note: The date formats for step 2 are whatever format 
your dates are in.
The result of the SUBDUR op code can be Months (*M), 
Days(*D) or Years(*Y)

Hope this helps,
