The Iron Spring PL/1 Compiler is a niche product currently available for OS/2, with plans for a commercial version that will be significantly cheaper than competing IBM products. The community expresses skepticism regarding the viability of the commercial version due to the declining market for PL/I. User comments highlight the decision to keep the product closed-source, with concerns over long-term accessibility should the developers cease operations. Furthermore, there are suggestions that including Windows support could enhance user adoption significantly. Some users reminisce that this product might have thrived in the 1990s but now faces significant challenges due to the shrinking demand for programming in PL/I today, with open-source alternatives being recommended for longevity and accessibility.
