I totally agree: is there a way to cast this as a single regression:

preserve
keep if cond3==1 & age>=15 & age<=64 & dipind==1 & hours>20 & hours<55
reg lwage i.fem##i.occupation##c.(pexper pexpersq edu2 edu3 child12 married northe centre south ftc partime d09)
restore
If some of the parenthesized variables are categorical, rewrite the latter as
(c.pexper c.pexpersq i.edu2 i.edu3 c.child12 ... )
You can then use margins to produce coefficients or conditional means for any combinations of gender and occupation.
