= Split line.

        SPLit {CONT | OVER | ALL | EXP | TAIL} [SBCS] [TOL] {STRDELM]
               [width] ["str"] [.lab1 .lab2]

            -CONT:process long lines splitted by the width of /M option
                  of EDIt cmd.
            -OVER:additional to CONT, process long lines of
                  line-length>width-of-parm.
                  If "str"(delimiter) option specified,the long line is
                  splitted by the delimiter at the nearest to the width.
            -ALL :process all lines. Default.
               Split line by delimiter char in the "str" and width.
               Diffently with CONT,short line is joined up to the with
               checking delmiter.
               If width parm is missing,width of /M parm of Edit
               /Browse cmd is used.
               If "str" parm is missing,line is splitted by just
               the width.In the case DBCS is splitted by width,
               both byte is shifted to the next line unless SBCS option
               specified.
               If both of width parm and /M parm missing,
               line is split simply by all delm char or delm string.
            -EXP :"str" char is padded to end of the line up to the width.
            -TAIL:Chars in the "str" is removed from end of the line.
                  With width parm,removed up to the width.

            -SBCS:No consideration to DBCS on width boundary.
                  This is always true forbynaly opened file.
            -TOL :split line with delemeter at top of line.
            -STRDELM:str parm is not delimiter characters but a string.
            -width:specify new width except for the type CONT.
                   To change display width of binary file simply enter
                   like as "SPL 100". Binary file display width can be
                   changed by this cmd even when browse mode.
            -str :delimiters. 1 delimiter char for EXP option.
                  treated as string when STRDELM option used.
            -.lab1/2:line range correspond to label on lineno column.
