--- Comment #3 from Simon Sobisch <simonsobisch at gnu dot org> --- As noted: this is an extension (possibly from ACUCOBOL, supported in GnuCOBOL). It _may_ compile (ideally only depending on the dialect). It is definitely not supported by IBM compilers - but those yield a better error message than the last GCC tested. The biggest issue here was that it _was_ supported in GCC, but only for the "UP BY n" part, not the "TO n" part; either both should have (possibly the same) reasonable diagnostic or both should compile. @Marty: is this improved now?
