FILE
The word FILE appears in the lower left corner of the industrial
terminal screen.
Here is an explanation of each value:
This Value: Stores This:
Counter address Address of the instruction's file position in the accumulated
value area of the data table.
Position Current word being operated upon (accumulated value of
the counter).
File Length Number of words in file (preset value of the counter).
File R Starting address of the destination file.
Word Address Address of source input word into the file.
This instruction duplicates and transfers the data of a word within your
source file to a specified word elsewhere in the data table. Here are some
characteristics of a File-to-Word Move instruction:
Programmed as an output instruction; requires four words of the user
program area.
Your program must externally index the counter. The explanation of
external indexing is the same for the File-to-Word Move instruction as
the Word-to-File Move.
