Syntaxes for DataWindow data expressions

This section describes in detail the syntaxes that were summarized in “About DataWindow data expressions”.

You can think of the syntaxes as grouped in three categories:

• Expressions with a named column or computed field

  • “Syntax for one or all data items in a named column”

  • “Syntax for selected data in a named column”

  • “Syntax for a range of data in a named column”

• Expressions with column numbers

  • “Syntax for a single data item in a DataWindow”

  • “Syntax for data in a block of rows and columns”

• Expressions that access whole rows

  • “Syntax for data in a single row or all rows”

  • “Syntax for all data from selected rows”
