GetSubstKeyCount

Syntax

GetSubstKeyCount(tbl_file);

tbl_file

A string specifying the path and filename of the substitution table.

Description

Returns the number of entries in a substitution table.

Returns

The number of entries in the substitution table specified by tbl_file.

Example

In this example, the following substitution table (author.tbl) is used.

//!CodePage UTF8! //!multicolumn! agatha christie 1890 alfred hitchcock 1899

The following script returns the number of entries in author.tbl:

$numRow = GetSubstKeyCount("../data/tables/author.tbl");

When the script is run, the variable $numRow gets the value 2.

Notes

•	A substitution table is kept in memory until the script function EraseSubst is called for that table.

•	For backwards compatibility, Subst and SubstArr do not remember comments made in the substitution file. If you want WriteSubst to keep your comments, call GetSubst before any other substitution function accesses the substitution file.
