The L command causes PX9EDT to print the limits. The top line in the buffer is the line
entered with the I command, and has no line number. The bottom line is the last line of the
object file, line 6.
The next command and the resulting interaction are as follows:

The F command scans for the character string B0002 with the verify and print options. The
replacement string, BOOOE, changes the memory address of workspace register 1 to that of
workspace register 7 in two instructions. Verification and printing provides control and documen-
tation of the changes.
The next command and the resulting interaction are as follows:

The F command scans for the character string 7F151, which is a checksum tag character and
associated field. The replacement character string is a null string, and the result is to remove the
checksum from a record which was changed by an edit command not
~hown
here.
The next command and the associated entry are as follows:
?I
AOOECB0227AOOFOB06C7A010AB04CTF
A010CB10FFF
The I command inserts the associated two lines following the line on which the pointer had been
positioned by an edit command not shown. The first line will cause the loader to overlay three
words of the original file, which is another way of changing object code. The second line is an
added instruction which will increase the size of the program module.
