Usage Notes for the DATE Function

Consider the following information when you use the DATE function:

The standard REXX date format B is the number of whole days since and including the base date, January 1, 0001. This number excludes the current day, because it is incomplete. For example, the following code would set var to the date today in format B:
```
var = DATE('B') + 1
```
And the following code would set var to the date two weeks from today in format B, assuming year end is not crossed:
```
var = DATE('B') + 15
```
B format conversion decrements the source-date, even if it is supplied in B format. For example, the following code returns 731246 from the OPS/REXX DATE function:
```
var = DATE('B',731247,'B')
```
The same conversion in standard REXX does not decrement the date.
When converting from B to any other format, standard REXX adds one day to the resulting date, whereas OPS/REXX does not.
