StringSub - method of object Pm

Returns the substring of another string
StringSub(sString As String, nStart As Long, [nEnd As Long]) As String
sString2 = Pm.StringSub(sString, nStart[, nEnd])
sString(String) Source string expression.
nStart(Long) Index in the string where the requested substring is to start. If this argument is negative, then it defines the position from the end of the string. It means that the number -1 indicates the last character, -2 the one before last, etc.
nEnd[optional] (Long) Index in the string that follows right after the substring ends.
If not set, then the substring contains all characters up to the end of the string.
If the argument is negative, then the cgaracters are counted from the end of the string.
The method can also be called in the graphic item events for Web panels.

The method is functional also in Macro expression $.expr and in the onDraw event of the PmiCanvas graphic item.
