DELETE a FILE in MD: using KAREL(FILE NAME TOBE EXTRACTED FROM DATA STRINGS REGI

    I'm Newbie to KAREL WORLD, Could somebody help me with the karel code to--

    Deleting a FILE in MD: using KAREL.pc program(FILE NAME TOBE EXTRACTED FROM DATA STRINGS REGISTERS)

    As a first step I am trying to create a .KL FILE in ROBOGUIDE9.0 to just delete a file using file name as below, I'm missing something need help to debug or correct code

    PROGRAM DELPRGLB
    VAR
    status : INTEGER -- The status returned from the built-in calls
    file_spec : STRING[30] -- The created file specification for DELETE
    BEGIN
    DELETE_FILE (MD:\BALA.TP, FALSE, status) -- Delete the file.
    IF (status <> SUCCESS) AND (status <> 10003) AND
    (status <> 85014) THEN
    WRITE (’ERROR ’, status,’ IN attempt TO delete ’,CR, file_spec,CR)
    ENDIF
    END DELPRGLB

    Hello,
    I've adjusted the code a little:
    PROGRAM DELPRGLB
    VAR
    STATUS : INTEGER -- The status returned from the built-in calls
    file_spec : STRING[30] -- The created file specification for DELETE

    BEGIN
    DELETE_FILE ('MD:\BALA.TP', FALSE, STATUS) -- Delete the file.
    IF (STATUS <> 10003) AND (STATUS <> 85014) THEN
    WRITE ('ERROR', STATUS,'IN attempt TO delete',CR, file_spec,CR)
    ENDIF
    END DELPRGLB


    I have some remarks:
    1. Always format your code in order to look easier to read.
    2. You have to enclose MD:\BALA.TP in ' '.
    3. You must enclose ’ERROR ’ .. in ' ', not in ’ ’.
    4. Variable SUCCESS is not declared.

    Awesome, Thank you very much Mr. Andreic, it worked.

    As I said as next step I want to choose\take the .TP file name for deletion from the char_array send from PLC.

    So I am thinking if I can modify the karel.pc with a dynamic String registers SR[1} (instead of a single definite file name) like the way I call in TP programs for program execution

    some thing like the attached Pictures


    Any Help :help:

    Hi Andreic,

    Going back to our previous conversion on deleting programs, the karel P-code got generated and I was able to execute the pc program and the intended program got deleted successfully, and the program is no longer seen in Teach pendant.

    But I get an error " uninitialized data type used'. as attached in picture

    Is this because the file is deleted and our karel is still trying to return a status of ,' I am not sure.

    file_spec is uninitialized.
    In this case you can see in your program. But you also can check by pressing ENTER on KAREL prog and selectes DATA -> Karel Vars.
    You must set file_spec to whatever you want, I guess the path of your file, so:
    Add file_spec='MD:\BALA.TP' replace DELETE_FILE (MD:\BALA.TP, FALSE, status) with DELETE_FILE (file_spec, FALSE, status).
