If you wish. you can have the system locate a sequence of characters
in a line and print that line up to those characters. You can then type
new characters to complete the line and enter the new line when you
press the RETURN key. For example, assume that you want to change the
characters "TUESDAY" to "THURSDAY" in the following line:
00015 PARTS DELIVERIES ARE MADE ON TUESDAY
Your listing will look as follows:
change 15 /tuesday
00015 PARTS DELIVERIES ARE MADE ON thursday
If the characters you want to change are in the line indicated by the
current line pointer, your listing would look like this:
change
*
/tuesday
00015 PARTS DELIVERIES ARE MADE ON thursday
You can also request that the system print out a specified number of
characters of a given line. Then you can enter the characters you want
to replace the remaining characters in the line. For example, you can
request that the first 26 characters of the line "PARTS DELIVERIES ARE
MADE ON TUESDAY" be printed:
change 15 26
00015 PARTS DELIVERIES ARE MADE after thursday
yOU
can have the system print the first several characters of a range
of lines. This is particularly useful when you want to change a column
in a table. For example. assume that you have the following data set:
00010
00012
00014
00016
00018
