(Maybe we could recommend an alternative approach, or > maybe not.) I'm leaning more and more towards the position that unconditional substitution would either have to be banned in 'foreign' or should be user configurable (as in "foreign language=R --strsubst=on"). Because I have verified that the "@" character also has its own meaning in R: https://stat.ethz.ch/R-manual/R-devel/library/methods/html/slot.html So if a script author requests string substitution for a foreign block, it would be her/his responsibility to avoid such ambiguities. It could also be useful to have this choice on a block-per-block basis and not for the entire script (as the above suggestion would ensure). Don't know how much effort the implementation would imply. thanks, sven _______________________________________________ Gretl-devel mailing list Gretl-devel(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-devel
