Joining this possibility with a mark-up language interspersed into the F90 code it is possible to use the source code itself as the source for documentation and Man Pages, in a way analogous to PERL 5.0 PODs. A simplified mark-up language is introduced here. The SGML syntax (i.e. marks with the form <mark-name> ... </mark-name>) is used to allow future expandability toward XML/SGML interpreters. In order to avoid interfering with the F90 compiler marks are added to comments so that the compiler will skip it.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering
