CALL 85 – Transfer
BASIC Output Buffer to
DH485 Common
Interface File Purpose
Use CALL 85 to transfer up to 40 words to the DH485 Common Interface File.
This routine has two input arguments and one output argument. The first input
argument is the starting word offset of the DH485 Common Interface File. If the
word offset value is not within the range 0 to 127, the output argument equals 1.
The second input argument is the number of words to be transferred from the
module output buffer to the DH485 Common Interface File. If the second input
argument number is not within the range 1 to 40, the output argument equals 2.
The output argument specifies the transfer status. It can have one of the following
values:
•
0 - Successful transfer
•
1 - Illegal starting offset
•
2 - Illegal length
Word integrity is guaranteed during this transfer. File integrity is not.
