Convert RPG Datefield %DATE into a signed numeric

To convert a RPG DATEFIELD to this numeric 8,0 field with no ‘/’ or ‘-‘ do this:

RPG Code Snippet
D USADate 8s 0 USADate = %dec(%char(DateField:*iso0):8:0);

Or another even neater function is this:

USADate = %uns(%char(DateField:*USA0));

I prefer this %UNS built in function, since it does not require me to specify length and decimal position parameters.

What is %UNS?

%UNSH (Convert to Unsigned Format with Half Adjust)

%UNSH(numeric expression)

%UNSH is like %UNS except that if the numeric expression is a decimal or a float value, half adjust is applied to the value of the numeric expression when converting to unsigned type. No message is issued if half adjust cannot be performed.

result1 = %uns (p7) + 0.1234; // "result1" is now 8236.12340
result2 = %uns (s9); // "result2" is now 23.00000
result3 = %unsh (f8); // "result3" is now 174.00000
// %UNS and %UNSH can be used as array indexes
a = array (%unsh (f8));
