Mark the current tape cell with the given name.
The mark command adds a text “tag” to the current tape-cell.
This allows the tape cell to be accessed later in the script with
the go
command. The mark and go commands should allow “offside
” or indent parsing (such as for the
python language)
The mark command has 2 formats, one with a parameter and one without:
mark; mark "here";
See the go
command for an example.
See the script pars/eg/markdown.toc.pss
for an example of using
the “mark” and “go” commands to create a table of contents for
a document from markdown-style underline headings.
