Question about calc syntax

[JWSch]

I see in an existing spreadsheet the following function call:

=INDEX($A7:$AMJ7;MaxIndex23)

and I am not aware of the “AM” syntax used in $A7:$AMJ7.

Searching in documentation don’t help me.

AMJ is a column reference, specifically the last column of 1024 available.

Thank you, that helps me.

You should consider to accept the answer by @robleyd as the solution.
