LOCAL lnSuccess
LOCAL loSb
LOCAL lnRemoveFlag
LOCAL lcResult

lnSuccess = 0

loSb = CreateObject('Chilkat.StringBuilder')

* Load a file that contains this string:  0123456789ABCDEF
lnSuccess = loSb.LoadFile("qa_data/txt/remove_chars.txt","utf-8")

* Return "56789A" from the string.
* if removeFlag is 1, the returned string is also removed from the sb.
lnRemoveFlag = 1
lcResult = loSb.GetRange(5,6,lnRemoveFlag)

? lcResult
? loSb.GetAsString()

* Output is: 
* 
* 56789A
* 01234BCDE
