Slide 17 of 68
Notes:
Getting onto the intermediate topics, we begin with the F$SEARCH lexical function.
F$SEARCH() is useful for finding files using both absolute and wildcarded file specifications.
If the file you specify is not found, F$SEARCH returns a null string.
If you supply a wildcarded filespec, F$SEARCH returns the next matching filespec on each subsequent invocation. When there are no more matching files, a null string is returned.
