This don't works for me. I got the macro `line' from -file read-. The file I
read may contain lines with single quotes and/or macro names. To wrote this
line (after some selections and/or replacements) to another file I use file
write. To use the _char(96)-solution I need to substitute single opening
quotes with something like:
local line: subinstr local line `"`"' `"_char(96)"'
which does not work.
Here is a (very) simple example of the problem. Consider the
following sequence:
file open texfile using saving.tex, replace write text
file open dofile using using.do, read text
file read dofile line
while r(eof)==0 {
file write texfile _n `"`line'"'
file read dofile line
}
file close dofile
file close texfile
This should "copy" the file using.do to the file "saving.tex" line by line.
It works---but not for lines with local macros...
