Follow-up Comment #17, bug #65474 (group groff): My posting (comment #14) was an answer to comment #11 (Paul Eggert).
The example, with a possible explanation .pl 3 .de MY .ie '\\$1'a' CASE a .el .ie '\\$1'b' CASE b .el CASE z .. .ie '1'1' \{\ . ie '1'2' .el .MY a\" groff processes this according to the output .\". el .MY a .\} .el NOTREACHED The ".ie '1'2' .el .MY a" is probably processed as ".ie '1'2' & .el .MY a" Tested with that line. So the probable execution is .ie '1'1 \{\ \" true .ie '1'2' .el .MY a\" false .\} .el NOTREACHED .NB. The whole text can be used as a input to nroff. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?65474> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
