Dos Unit
Searches for a file.
Declaration:
function FSearch(Path: PathStr; DirList: string): PathStr;
Remarks:
Path is of type PathStr which is defined in the Dos unit.
DirList is a list of the directories to include in the search each
delimited with a semicolon (;).
FSearch returns the directory and file name if the file has been
located. If Path is not found then an empty string is returned.
FSearch always begins with the current directory and then checks
the directories listed in DirList in the order that they appear.
Example:
uses
Dos,Strings;
var
DosPath,
TreePath: String;
File : PathStr;
begin
DosPath := GetPath;
File := 'TREE.COM';
TreePath:= FSearch(File, DosPath);
if Empty(TreePath) then
Halt(1);
TreePath := AppendBKSlash(TreePath);
Exec(TreePath + File,'');
end.
