What are the wildcards for FILE_MASK in FM EPS_GET_DIRECTORY_LISTING

Question

The wildcard for exactly 1 character is '?'.
example: with mask ????????.STA     , I get the following files:
BWMDAACW.STA
BWMDAADW.STA
BWMDAAEW.STA
BWMDAAFW.STA
BWMDAAGW.STA
(all files ending with .STA, with 8 characters before .STA)
But what is the wildcard for 'any character' ?
I tried with *.STA     , but the result is
test1
test2
test3
test4
y5c01
(all the filenames with exactly 5 characters)
with *STA, the result is
IBAN
PBCL
rfbi
stxh
stxl
(all the filenames with exactly 4 characters)
(the result is the same with *123 or *XYZ !!!)
with BW*, the result is
BWMDAACW.STA
BWMDAADW.STA
BWMDAAEW.STA
BWMDAAFW.STA
BWMDAAGW.STA
as expected, but * seems the right wild character for 'any character' only at the end of the mask; it seems not work as expected when it is not the last character of the mask.
It seems very strange! What are the rules for wildcards ? (I'm in 4.7)
thanks in advance
