- HANDLES.HLP Hnadles documentation
-
- HANDLE ( | name --- )
- creates an array/handle for name, which holds the files
- attributes, handle number, and null terminated name.
-
- >ATTRIB ( handle --- attrib-addr )
- Step to the attribute field of the handle.
-
- >HNDLE ( handle --- handle-addr )
- Step to the handel storage field of the handle array.
-
- >NAM ( handle --- name-string-addr )
- Step to the null terminated name field of the handle
-
- FILE1 ( --- a1 )
- FILE2 ( --- a1 )
- Define a couple of handles for testing
-
- DEFEXT ( --- a1 )
- An array holding the default extention "SEQ".
-
- ?DEF.EXT ( --- )
- If the specified file name has no "." indicating the
- extension, then supply one from the default.
-
- $>HANDLE ( filename1 handle1 --- )
- Move a counted filename1 string into handle1 for use by
- the following words.
-
- !HCB ( a1 | name --- )
- Get "name" from the input stream and move it into the handle a1.
-
- FCB>HANDLE ( a1 a2 --- )
- Copy the file name and extention from the specified FCB a1 to
- handle a2.
-
- HANDLE>EXT ( a1 --- a2 )
- Moves the address from the handle to the decimal point in the
- filename, if it exists. Otherwise it steps to the null
- immediately following the filename.
-
- $>EXT ( a1 n1 a2 --- )
- Move the specified string a1,n1 to the extension field of the
- handle a2. The string a1,n1 should be the file extension excluding
- the decimal point. i.e. " XYZ" not " .XYZ"
-
- HDOS1 ( cx dx fun -- ax cf | error-code 1 )
- Define a dos call assembly word, which is later used by
- HOPEN and HCREATE.
-
- HDOS3 Yet another DOS call.
- HDOS4 Still another native DOS call.
-
- MovePointer ( double-offset handle --- )
- Move the file pointer for handle to the position
- double-offset in the file already open in handle.
-
- EndFile ( handle --- double-end )
- Return the double-end pointer for the file open in
- handle, also sets the pointer to the end of the file.
- Useful for finding the end of a file, and for appending
- to the end of a file.
-
- PATHSET ( handle --- f1 )
- Set the current drive path into handle. returns boolean f1
- true if an error occured while performing this operation.
-
- <HRENAME>
- Code primitive for the HRENAME function below.
-
- HRENAME ( handle1 handle2 --- return-code )
- Change the name of the file specified in handle1 to the
- name specified in handle2. Can be used to move a file
- from one directory to another on the same drive.
- Returns 18 if the rename was good, not zero.
-
- HCREATE ( handle --- error-code )
- Create the file specified in handle, if the file already exists,
- then it is ZEROed !! Returns zero if no error occured. The file
- is automatically created ready for write operations.
-
- RWMODE ( --- a1 )
- The variable rwmode, which defaults to a value of 2,
- controls the read write mode of the file being opened,
- the value 2 is read, or write, a value of 1 specifies
- write only, and a value of 0 specifies read only.
-
- R/W-DMODE ( -- n1 )
- Return the value of the current default read/write mode. This
- value is used to restore the default mode after each HOPEN is
- performed. See also DEF-RWMODE
-
- DEF-RWMODE ( -- )
- This word allow you to set the default read/write mode used
- by F-PC for all file open operations. It is used as follows:
-
- READ-WRITE DEF-RWMODE
- or READ-ONLY DEF-RWMODE
-
- All further file open operations will be in the newly
- specified mode.
-
- READ-ONLY ( -- )
- The next file opened can be accessed with read operations only.
-
- READ-WRITE ( -- )
- Open a file for read and write operations. See also READ-ONLY
- and WRITE-ONLY.
-
- WRITE-ONLY ( -- )
- Open a file for write only. See also READ-ONLY and READ-WRITE.
- This word and the previous two words effect only the next HOPEN
- operation to be performed. After the open is done, RWMODE
- reverts to the default mode for later file opens.
-
- HOPEN ( handle --- error-code )
- Open the file specified in handle, return error-code zero if the
- file was opened properly. Unless otherwise specified, the file is
- opened for both read and write operations.
-
- HCLOSE ( handle --- f1 )
- Close the file specified by handle, return bool f1
- non-zero if an error occured.
-
- HDELETE ( handle --- f1 )
- Delete the file specified by handle, return bool f1
- non-zero if an error occured.
-
- EXHREAD ( a1 n1 handle seg1 --- n2 )
- Read from the file specified by handle to the extended segment
- area specified by seg1, a1 for length n1. Returns n2 the
- length actually read.
-
- EXHWRITE ( a1 n1 handle seg1 --- )
- Write from memory a1,n1 in segment seg1 to the file specified
- by handle.
-
- HWRITE ( a1 n1 handle --- n2 )
- Write to a file specified by a handle from a1,n1 in the code
- segment. Return n2 the length actually written.
-
- HREAD ( a1 n1 handle --- n2 )
- Read from a file specified by a handle to a1,n1 in the
- code segment. Returns n2 the length actually read.
-
- FINDFIRST ( string --- f1 )
- Begin a search for files specified by filespec string.
- String is a null terminated un-counted string. F1 returned
- indicates whether any files matched. The found file is placed
- in the Data Transfer Area (DTA).
-
-
- FINDNEXT ( --- f1 )
- Continue the file search for a specified string. Returns
- the bool f1 true if another match was found.
-
- SET-DTA ( a1 --- )
- Set the Disk Transfer Area as a1.
