Syntax

FINDFILE(file-specification,context)

file-specification: specifies the file specification of the file that you are searching for. It can contain any valid OpenVMS file specification, including wildcards. The value for file-specification can be a character variable, a character literal enclosed in quotation marks, or another character expression. You must have access to the file that you are searching for.
context: is a variable used internally by the SAS System to maintain the search context between executions of FINDFILE. It must be initialized to 0 before the first execution of FINDFILE for a given file-specification and must not be modified between executions. Context must be a numeric variable initialized to 0; it cannot be a literal 0. You can use FINDFILE for multiple search streams by specifying a different context variable for each stream. For example, you can have variables named CONTEXT1 and CONTEXT2.

context=0;
fn=findfile('myprog*.sas',context);
do while (fn ^= ' ');
   put fn;
   fn=findfile('myprog*.sas',context);
end;
