POSLOWER()
 Finds the position of the first lower case alphabetic character
------------------------------------------------------------------------------
 Syntax

     POSLOWER(<cString>,[<lMode>],[<nIgnore>])
        --> nPosition

 Arguments

     <cString>  Designates the string that is searched.

     <lMode>  Designates how the function searches for the first lower
     case alphabetic character.  The default value (.F.) searches for the
     first alphabetic character that can be changed by the CA-Clipper
     function UPPER().

     <nIgnore>  Designates the number of characters at the beginning of
     the character string that are excluded from the search.  The default
     value excludes none (0).

 Returns

     The value returned corresponds to the position of the character located.
     When no matching character is found, the function returns 0.

 Description

     Starting from the beginning of the string, POSLOWER() searches for the
     first lower case alphabetic character in <cString>.  If <lMode> is .T.,
     the function searches for the first non-alphabetic character that would
     not be changed by UPPER().  The <nIgnore> parameter excludes a specific
     number of characters at the beginning of the <cString> from the search.

 Notes

     .  Characters located when the <lMode> parameter is designated as
        .T. are not necessarily upper case, alphabetic characters.

     .  The function works in conjunction with the NATION module
        because different languages use different characters to represent
        their alphabets.

 Example

     cString  :=  "123ABCuabc"

     ? POSLOWER(cString)                 // Result: 7
     ? POSLOWER(cString, .T.)            // Result: 1
     ? POSLOWER(cString, .F., 7)         // Result: 8
