1.0 and 2.0 on both device and desktop. There are two objects, StringsEx and
StringBuilder, included in this library. This help file documents version1.1 of the
library.</span></font><p style="margin-left:0mm; margin-right:0mm; text-indent:0mm; margin-top:1.76mm; margin-bottom:1.76mm;"><font face="Times New Roman"><span style=" font-size:12pt"><b>StringsEx </b>provides some additional string manipulation functions. As with all
Basic4PPC (.NET) strings the original string is not altered but a new string containing
the required contents is returned. Some of the methods provided can already be
synthesised using existing Basic4PPC String handling, such as EndsWith, but are
more efficiently implemented here. Also the explicit titling of such methods can make
the intentions of code clearer.</span></font><p style="margin-left:0mm; margin-right:0mm; text-indent:0mm; margin-top:1.76mm; margin-bottom:1.76mm;"><font face="Times New Roman"><span style=" font-size:12pt"><b>StringBuilder </b>provides a high performance way to concatenate many strings. As
stated above .NET strings are not "mutable" so concatenating (appending) two strings
needs memory to be allocated for a third string and the two strings copied into the
memory. This is inefficient when concatenating many (say more than ten) strings so
for this reason the StringBuilder is available. A StringBuilder is a "mutable" string. It
allocates memory once and copies the content of strings to be appended to this
memory so saving memory allocation and multiple copies of earlier appended string
data to a new string. Also a StringBuilder can grow itself if its' initial capacity is not
enough. </span></font><p style="margin-left:0mm; margin-right:0mm; text-indent:0mm; margin-top:1.76mm; margin-bottom:1.76mm;"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font><p style="margin-left:0mm; margin-right:0mm; text-indent:0mm; margin-top:1.76mm; margin-bottom:1.76mm;"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font><p style="margin-left:0mm; margin-right:0mm; text-indent:0mm; margin-top:1.76mm; margin-bottom:1.76mm;"><font face="Times New Roman"><span style=" font-size:12pt">A.
