Sub

 

Sub>Value,Number

 

Subtracts a number from a value.  Deprecated by Let for numeric calculations.

 

Interpreted as Value = Value - Number

 

Value must be a variable containing a numeric or date value.  Number can be either a literal number or a variable containing a numeric value.

 

For date values this function will subtract the number of days, represented in Number from the given date value.

Will now do the same thing.
