Overwriting Data in an Existing File (Third Digit of C=1)
FWRIT(701) uses data area data starting at the word specified in S to over-
write file memory data in the specified data type. It overwrites the number of
words or fields specified in D1 and D1+1 in the file specified in D2 (with file-
name extension .IOM, .TXT, or .CVS) starting at the address specified in
D1+2 and D1+3.
Appending Data to an Existing File (Third Digit of C=0)
FWRIT(701) appends data area data starting at the word specified in S to a
data file in file memory in the specified data type. It appends the number of
words or field specified in D1 and D1+1 to the file specified in D2 (with file-
name extension .IOM, .TXT, or .CVS).
Creating a New File with Source Data
If the file specified in D2 does not exist, FWRIT(701) creates a new file with
that name and filename extension (.IOM, .TXT, or .CVS) and writes the speci-
fied source data in the specified data type starting at the beginning of the file.
In this case, it does not matter if appending to overwriting data is specified.
