Acuserve load bitmap and dll

Hello!

I need help for load bitmap and DLL for acuserver. See my configuration:

1-Config

CODE_PREFIX @192.168.0.222:F:\IMP\ACUSERVE\PDV\OBJ;@192.168.0.222:F:\IMP\ACUSERVE\PDV\OBJF;@192.168.0.222:F:\IMP\ACUSERVE\PDV\OBJC;.
FILE_PREFIX @192.168.0.222:F:\IMP\ACUSERVE\PDV\DADOS;@192.168.0.222:F:\IMP\ACUSERVE\PDV\DADOSR;@192.168.0.222:F:\IMP\ACUSERVE\PDV\DADOSP

|for load image and DLL  (not working)

IMAGE_PREFIX @192.168.0.222:F:\IMP\ACUSERVE\PDV\IMG
DLL_PREFIX @192.168.0.222:F:\IMP\ACUSERVE\PDV\DLL

to solve I mapped the network, but is problematic!

IMAGE_PREFIX I:\ACUSERVE\PDV\IMG
DLL_PREFIX I:\ACUSERVE\PDV\DLL

2-Load image 

ACCEPT WEXT-IMG-PREFIX FROM ENVIRONMENT "IMAGE_PREFIX".
|CARREGAMENTO DA IMAGEM
INITIALIZE WX100
STRING WEXT-IMG-PREFIX DELIMITED BY SPACES
'\LOGOEMP.JPG' DELIMITED BY SIZE
INTO WX100
END-STRING
CALL "W$BITMAP" USING WBITMAP-LOAD,
WX100 GIVING LOGO-JPG
END-CALL

3-load DLL

ACCEPT WEXT-DLL-PREFIX FROM ENVIRONMENT "DLL_PREFIX".
SET ENVIRONMENT "DLL-CONVENTION" TO "1".

INITIALIZE WPATH-DLL.
STRING WEXT-DLL-PREFIX DELIMITED BY ' '
"\RPSIMPX.dll" DELIMITED BY SIZE INTO
WPATH-DLL.
CALL WPATH-DLL
ON OVERFLOW DISPLAY MESSAGE 'ERRO LOAD RPSIMPX.DLL'
EXIT PARAGRAPH
END-CALL.

I demonstrated how the CBLCONFI is configured. Note that IMAGE_PREFIX and DLL_PREFIX tried to use the same logic as CODE_PREFIX and FILE_PREFIX. However to no avail. When used through network mapping and not through the acuserve directive it works, however it would need the network mapping and if it were to be used with an external IP there would be no way to map as it would not be using the local network.
I couldn't find documentation regarding loading images and dll for acuserve. I would like to know what is the correct way to carry out both the loading of dlls and images for clients that use terminals through acuserve.
thanks
