CToDoW()

Convert name of day of the week to its ordinal number

Syntax

       CToDoW( <cDayName> ) -> <nOrdinal>

Argument

<cDayName> Name of day to convert to ordinal number

Return

<nOrdinal> Ordinal number of <cDayName>

Description

Use CToDoW() to change the name of a day of the week to a number. Sunday corresponds to 1, Monday 2, etc.. If the function returns a 0 value, an invalid parameter has been passed. You can shorten the day names, but these abbreviations must be explicit to return an accurate value.

Notes

. Uppercase and lowercase letters do not affect the name of the day of the week. . The function’s operation depends on the country-specific adaptation of your CA-Clipper compiler. With an English version of CA-Clipper, only English day names are recognized.

Example

          ? "CToDoW('Sunday') :", CToDoW('Sunday') // 1
          *  Show several ways to get the day of
          *  the week for Wednesday:
          ? "CToDoW('WEDNESDAY') :", CToDoW('WEDNESDAY')      // 4
          ? "CToDoW('Wednesday') :", CToDoW('Wednesday')      // 4
