. TCRWF
.TCRRD
Writes the contents of the buffer into a file .
The requested length of the file is the value of
buflen~th. If there is already a file of the
specif~ed name, it is deleted and the space is
reclaimed.
The requested size of the file "is specified by
buflength. If there is not enough space to write
the entire file, nothing is written, the ac is set
to the number of free words of space available to
the user, and the error return is taken.
If there is enough space, the file is written.
The ac is set to the amount of space left after
the file has been written and the skip return is
taken.
If insufficient space is available, none of the
file is written, the error return occurs, and the
number of free words available to your program is
returned in the ac.
Reads a directory. The number of .TMP files in
your directory is returned in the ac, and their
file names are written into the buffer for the
call. You can check for truncation of the
directory list by comparing the ac to buflength.
Each entry in the buffer is of the form:
XWD
'nam',length
In the argument word:
o
o
length is the length of the file in words.
nam is the file name.
