D.9.2.7 texname

Usage:

texname(fname,s); fname,s strings

Return:

if fname="": the transformed string s, for which the following rules apply:

s' + "~" --> "\\tilde{"+ s' +"}" "_" + int --> "_{" + int +"}" "[" + s' + "]" --> "_{" + s' + "}" "A..Z" + int --> "A..Z" + "^{" + int + "}" "a..z" + int --> "a..z" + "_{" + int + "}" "(" + int + "," + s' + ")" --> "_{"+ int +"}" + "^{" + s'+"}"

Furthermore, strings which begin with a left brace are modified by deleting the first and the last character (which is then assumed to be a right brace).

if fname!="": append the transformed string s to the file <fname>, and return nothing.

Note:

preceding ">>" are deleted in fname, and suffix ".tex" (if not given) is added to fname.
