94. IsInput

IsInput

This function evaluates whether there is an input value on the given slot at the given datetime.

Description	The input status of a slot at a given datetime.
Type	BOOLEAN
Arguments	Type	Meaning
1	SLOT	the series slot
2	DATETIME	the datetime
Evaluation	The datetime argument; which may be specified symbolically, is converted into an actual datetime. Then, the flag of the value in the series slot at that time is compared with the user input flags. If the flag is an “I” or “Z”, true is returned. An “i” is considered a user input within an iterative MRM run, but not a user input within a single run or outside of a run. The “R” flag is not considered an input. Also, IsInput returns false if the slot[datetime] is NaN. But, this function does NOT terminate the executing rule if the value at the given datetime is a NaN.
