EDIT special characters:
Replacement: ^B '" next match string
^O '* '*<number>'* is nth match string
^^ '7 quote next character
Match: ^E '% not
^N ') arbitrary number of
^T '/ any character
^^ '7 quote next character
^ ': separator
Positions: . present line or page
^ first line or page
* last line or page
EDIT definitions and meanings:
<range> ::= <pos>[!<number> or
:<pos>]
<pos> ::= [<line>][/<page>]
<line> ::= [<number> or
<content> or
. or * or ^][(+-)<number>]
<page> ::= [<number> or
. or * or ^][(+-)<number>]
<content> ::= $<string>$<range>,<foptions>
<number> ::= any positive integer .LE. 2^35-1
Options:
,D Decide on each substitution (S command)
,E Match upper/lower case characters Exactly (F and S commands)
,L Do not print contents of line (F, S, and X commands)
,A Enter ALTER mode (F and S commands)
,N Do not print line number (P command)
Special functions of the "I" command:
I<CR> default is set to end of last:
Replace, except at end of page
Insert, except wrap around or out of space
I/<page> does insert page mark at end of <page> followed by Istart,
where start is the value of the START switch (Originally,
the START switch is set at 100).
I<pos>!n allows insertion of n lines; calculates increment from
table of aesthetic values.
I^ inserts a line at the top of the page, halfway between line
0 and the first line.
EDIT Command Format:
@CREATE (FILE) /switches input.typ.gen
or,
@EDIT (FILE) /switches input.typ.gen (OUTPUT AS) output.typ.gen
CREATE requires that input.typ.gen is a new file; EDIT
works regardless of whether the file exists or not.
/switches is a list of settable switches which may
be recognized. If an illegal switch is encountered,
the entire command is ignored.
input.typ.gen, and output.typ.gen are TOPS-20 file
specifications; recognition is available. Output.typ.gen
defaults to input.typ.-1 if it is not explicitly typed.
