File Copy and File Fill Instructions
This chapter covers the following instructions for use with the fixed, SLC
5/01, and SLC 5/02 processors:
• File Copy (COP)
• File Fill (FLL)
These instructions move data from a source file or element to a destination
file. They are similar to a Move (MOV) instruction, but they enable you to
move more than one word at a time. This is facilitated by the use of the file
indicator # in the parameter addresses. The # symbol indicates a file or
group of words, not just one word.
The following general information applies to file copy and file fill
instructions.
Effect on Index Register in SLC 5/02 Processors
After a COP or FLL instruction is executed, index register S:24 is cleared to
zero.
