ahh!, spanta.DAT is the text shown in the screen saver....
and spanta.txt was a test file for testing purposes.
iirc, pressing F8, one of the screen savers appears.... mmmm.... in these short program, the screen saver are not enabled.
you see, i when programming in GWBASIC i use always the same library....
since the 10 - 9999 lines, are a lot of routines (windowing handling), datafile, printer handling, screen savers, menues handling, configuration load/save etc....
so, when i use big systems for companies i use the same platform than when i did this program for me. (well, if a insurance local company can be consider like a "big company"

, but what?, i was a teenage and i already did things like that....
mmmm... nah. i did one better, in GWBASIC, i did a tournament matcher with players database for the C.A.D.A. it is a club of chess, and the program gets the aprovation of a international chess judge. It does american tournaments and Swiss tournament.
