LINEDEL offers various ways for systematic removal of lines in the current edit field. LINEDEL does not save the edit field after the removal; it must be done by the user if needed. LINEDEL L1,L2 / deletes lines L1-L2. LINEDEL L1,L2,EMPTY / deletes empty lines from lines L1-L2. LINEDEL L1,L2,EMPTY,k / works similarly but when n consecutive empty lines are encountered, min(n,k) of them will be preserved. For example, if k=1, just one empty line will left in sequencies of empty lines. LINEDEL L1,L2,<string> deletes lines having any of characters in <string> in the control column from lines L1-L2. LINEDEL L1,L2,"<string>" / (<string> may contain shadow characters) deletes lines containing <string> from lines L1-L2. LINEDEL L1,L2,"<word1>","<word2>",... deletes lines containing all the words <word1>,<word2>,... LINEDEL L1,L2,STEP,s deletes lines L1,L1+s,L1+2s,L1+3s,... from lines L1-L2. LINEDEL / without parameters deletes empty lines below the command line to the first non-empty line. In all forms of LINEDEL (except in the second one "EMPTY") the deleted lines can be saved in a selected (new) edit file by giving the specification DEL_SAVE=<name_of_edit_file>. This option enables making smart selections of edit lines.
