Text specifies the string in which to search.
Index specifies a position in Text used to identify the word. If the character at Index position is part of a word, then GetLexemeBegin returns the begin index of that word.
If the character at Index position is not within a word in Text, then GetLexemeBegin returns 0.
Example:
index:=GetWordBegin('This is my string', 7)
//result
index=5
//the word starts at position 5:'is'
