@wspector - Converting DATAPOOL
The reason we converted DATAPOOL to COMMON, not to MODULE was historical. The first conversion was made in 1993 before Fortran 90 was widely accepted in the aerospace world where we then worked. However it was fortunate because:
i. We could easily map COMMON blocks between programs. I haven’t tried this with modules yet - perhaps others can comment?
ii. The Gould-SEL system has an interactive handler that will view and change values in DATAPOOL at run-time. We implemented this for the migrated DATAPOOL construct. Please see fpt Reference: BUILD ACCESS DATABASE
I think that if there is an interest in DATAPOOL we should start a new thread. Gould-SEL systems were used for a large number of training simulators for commercial and military aircraft, for military aircraft design simulators, power plant simulators and for instrument control - e.g. tracking radars. The original hardware has (I hope) died but the programs run in emulation of the MPX operating system at a surprising number of sites. Do any forum contributors have an interest in these?
