- 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.
-
- 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 opened for read and write
- operations.
-
- hopen ( handle --- error-code )
- Open the file specified in handle, return error-code
- zero if the file was opened properly.
-
- The file is opened for both read and 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.
-
- 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.
