ISREF

Tests if the argument is a reference to a cell or range of cells.

Syntax:

ISREF(value)

Returns TRUE if value is a reference to a cell or range of cells and FALSE otherwise.

Example:

ISREF(C5)

returns TRUE, because C5 refers to a cell.

ISREF(A1:B3)

returns TRUE, because A1:B3 refers to a range of cells.

ISREF("A5")

returns FALSE, because "A5" is text, not a cell reference.

ISREF(NA())

returns FALSE, because NA() is an error, not a cell reference.

ISREF(A9999999)

returns FALSE, because cell A9999999 does not exist.

ISREF(range1)

where range1 is the named range A1:B3, returns TRUE.

ISREF(range2)

where range2 is not defined, returns the #NAME? error

ISREF(INDIRECT(C1))

where cell C1 contains the text "D1", returns TRUE, because INDIRECT returns a reference.

Issues:

• The ODFF standard is not clear what ISREF should return when presented with an undefined range.

• TYPE

• Information functions

• Functions listed alphabetically
• Functions listed by category
