NUM-ENTRIES Function
Returns the number of items in a list.
SYNTAX
list
A list of strings—an entry list. (See the ENTRY Function reference entry.) NUM-ENTRIES returns the number of elements in the list. Specifically, NUM-ENTRIES returns the number of delimiters plus 1, and it returns 0 if list equals double quotes (
""
).character
A delimiter you define for the list. The default is a comma (,). This allows functions to operate on non-comma-separated lists. If you use an alphabetic character, this delimiter is case sensitive.
EXAMPLESThis procedure uses NUM-ENTRIES and ENTRY to loop through a list of regions and display them, one per line. Since there are obviously five regions, the REPEAT statement, REPEAT i=1 TO 5, works fine here.
In the following example, PROPATH is a comma-separated list of unknown length.
This procedure uses NUM-ENTRIES to loop through the PROPATH (a comma-separated list of directory paths) and print the directories, one per line.
This example uses a list that does not use commas as a delimiter. This procedure returns a value of 13.
NOTE
The NUM-ENTRIES function is double-byte enabled. The specified list can contain entries that have double-byte characters and the character delimiter can be a double-byte character.
