StrRemoveLastSlash
InstallShield 2020 » InstallScript Language Reference
The StrRemoveLastSlash function removes the trailing backslash from a path specification. Because its purpose is to produce a valid path, StrRemoveLastSlash does not remove the backslash from a root directory specification, such as “A:\” or “C:\”.
Syntax
StrRemoveLastSlash ( svPath );

Additional Information
StrRemoveLastSlash provides a convenient way to remove the trailing backslash from a path returned by AskPath or ParsePath. Because its purpose is to produce a valid path, StrRemoveLastSlash does not remove the backslash from a root directory specification, such as “A:\” or “C:\”; doing so would turn a valid path into a drive specification. If you need to remove the trailing backslash from a path in all cases, use the following script segment as a guide.
AskPath("", "", svPath);
if (StrLength(svPath) = 3)
&& (svPath[1] = ":")
&& (svPath[2] = "\\") then
svTempString = svPath;
StrSub(svPath,svTempString,0,2);
else
StrRemoveLastSlash(svPath);
endif;
