参数

cString (Optional)
类型：__Usual
String to check
lNoLetter (Optional)
类型：__Usual
When TRUE is passed then the first character is returned which is not changed by function Lower(). Defaults to FALSE.
nIgnoreCharsFromLeft (Optional)
类型：__Usual
Number of characters that must be ignored. Defaults to 0.

返回值

类型：Int32
Returns the position of the first upper case letter in a string as a numeric value, or ZERO when there is no uppercase letter in the string.
备注
In X# A letter is defined as a character for which the Char.IsLetter() method returns TRUE. If lNoLetter is set to TRUE the function returns the position of the first character which is not a letter.
