Finding And Positioning The Current; Line Pointer; Finding The Current Line Pointer - IBM System 360 User Manual

If you prefer" you can define tab settings by entering a line
containing tis in positions corresponding to desired tab settings. For
example, to establish tab settings in columns 10, 25, and 35 you can use
the TABSET subcommand as follows:
tabset image
123456789tbbbbbbbbbbbbbbtaaaaaaaaat
You must fill the spaces between the tis with blanks or characters
other than t. Do not use the TAB key when entering the IMAGE line, nor
the backspace except as a character-deletion character
If you want to nullify the existing tab settings for the data set,
enter the TABSET subcommand as follows:
tabset off
The maximum number of logical tab settings that can be defined is
ten.
Finding and Positioning the Current Line Pointer
Unless you plan to use line numbers for all your edit operations, you
should know how to find and reposition the current line pointer. These
operations are described in the following paragraphs.
FINDING THE CURRENT LINE POINTER
The location of the current line pointer is determined by the last
subcommand you entered. If you are editing an old data set, the current
line pointer is ppsitioned at the last line of the data set upon initial
entry into Edit mode. Figure 5 shows the location of the pointer at the
end of each subcommand. If you do not remember this information, you
can use the LIST subcommand with the
*
operand to find the line at which
the pointer is positioned. For example:
list
*
THIS IS THE LINE AT WHICH THE CURRENT LINE POINTER IS POSITIONED
You can also have the system display the line at which the pointer is
positioned every time the pointer changes as a result of the CHANGE,
TOP, BOTTOM, UP. DOWN. FIND and DELETE subcommands. To do this use the
VERIFY subcommand as follows:
verify
The VERIFY subcommand is in effect until you enter it again with the
OFF operand:
verify off
