Use EditBlank to replace current session text with blanks in a specified column range for a specified group of lines.
EditBlank may also be entered as EditBl[ank] or Bl[ank].
(The EditKeep command can be used to blank out columns in all BUT a specified range.)
The group of lines can be specified by pre-selecting the lines (see Selection) or by using the FCT operand. If neither a pre-selection or FCT operand is provided, the group of lines consists solely of the current line.
Optional Operands
ZONE is the column range to blank. Enter it in the format xxx-yyy where xxx and yyy are numbers between 1 and the session maximum line width. For example, ZONE=11-20 signifies columns 11 to 20. ZONE=5 is the same as ZONE=5-5, ZONE=5-* specifies columns 5 through the session maximum line width, and ZONE=-5 is the same as ZONE=1-5.
Default: current session zone.
FCT specifies the number of lines to update. If FCT is specified as an asterisk (*), all of the lines through the end of the session will be updated.
Default: 1.
Return Codes
OK Successful.
Examples
Blank all text in columns 6 to 13 starting at the current line and proceeding through to the last line of the session:
=> bl 6-13,*
