Enter a line command by performing one of these actions:
- Typing the command in the line command field and pressing Enter.
- Placing the cursor in the data or line command field and pressing
a function key to which the command is assigned.
These rules apply to all line commands:
- You can type several line commands and make multiple data changes
before you press Enter. The editor displays an error message if the
line command is ambiguous. Because the line commands are processed
from top to bottom, it is possible to have one error message appear
that masks a later error condition. Only the first error condition
found is displayed. After you have corrected that error condition,
processing can continue and the next error condition, if any, is displayed.
If you type a line command incorrectly, you can replace it before
you press Enter by retyping it, blanking it out, or entering RESET.
- Generally, you need to type over only the first 1 or 2 characters
of the line number to enter a line command. Sometimes, however, typing
a single character can be ambiguous. In this example, it is unclear
whether the intended line command is R to repeat
line 31700, or R3 to repeat the
line three times:
031600
R31700
031800
In such cases, the ISPF editor assumes that you
have not typed a number following the line command. If you want to
repeat the line three times, you can use any of these procedures:
- Leave the cursor on the character that immediately follows the R3:
R31700
- Type one or more blanks following the R3:
R3 700
- Type one or more blanks following the R but before
the number, leaving the cursor on the character that immediately follows
the 3:
R 3700
- Type R3 and press the Erase EOF key to clear
the rest of the line command field, or press the Erase EOF key and
then type R3
- You can type these line commands on the TOP OF DATA line
by typing over the asterisks that appear in its line command field:
- I, In
- Insert one or n lines ahead of the data.
- A, An
- Move or copy a line or lines one or n times
ahead of the data.
- TE, TEn
- Type one or n text lines ahead of the
data.
- You can type this line command on the BOTTOM OF DATA line
by typing over the asterisks:
- B, Bn
- Move or copy a line or lines one or n times
following the data.
