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.
