6.6 Advanced ED Commands CP/M 3 User's Guide
If you combine this command with other commands, you must terminate the
delete-to string with a CTRL-Z or ESC, as in the following example. If an uppercase
J command letter is specified, ED looks for upper-case search and delete-to
strings and inserts an upper-case insert string.
The J command is especially useful when revising comments in assembly language
source code, as follows
236: SORT LXI H, SW ;ADDRESS TOGGLE SWITCH
236: *j;^ZADDRESS SWlTCH TOGGLE^Z^'L^ZOLT
236: SORT LXI H, SW ;ADDRESS SWITCH TOGGLE
236: *
In this example, ED searches for the first semicolon and inserts ADDRESS SWITCH
TOGGLE after the mark and then deletes to the sequence, represented by
CTRL-L. In any search string, you can use CTRL-L to represent a when
the phrase that you want extends across a line break. You can also use a CTRL-1 in
a search string to represent a tab.
Note: if long strings make your command longer than your screen line length, enter
a CTRL-E to cause a physical carriage return at the screen. A CTRL-E returns the
cursor to the left edge of the screen, but does not send the command line to ED.
Remember that no ED command line containing strings can exceed 100 characters.
When you finish your command, press the carriage return key to send the command
to ED.
The M (Macro) Command
An ED macro command, M,, can increase the usefulness of a string of commands.
The M command allows you to group ED commands together for repeated execution.
The M command takes the following form:
nMcommand string
where n is the number of times the command string is to be executed. A negative
number is not a valid argument for an M command. If no number is specified, the
special character # is assumed, and ED executes the command string until it reaches
6-24
