HELP TO RUN QBASIC CODE FROM 90s !

[musss1]

[*]Prog.2.0 -  "DATAFILE UFLO"
[*]Prog.2.1 - "EXHAUST"
[*]Prog.2.2 - "INDUCTION"
[*]Prog.2.3- "CYL-PIPEFLOW"

[*]Prog.5.1 - "ENGINE MODEL NO.1"
[*]Prog.5.2 - "ENGINE MODEL NO.2" .

here guys
im using ONLY the program "(5.2)" , with the specific subroutines for that particular program!, the programs 2.1 - 2.2 - 2.3 are similar, but i think they RUN completely separated, likewise prog 5.1 and 5.2, although they need the (datafile.uflo)
apart from that, i cant go more in depth, i will check the syntax again,

heres the pdf with all the info
