st: problem with do file stopping prematurely

["Christopher W. Ryan" <cryan@binghamton.edu>]

I composed the following do file in Crimson editor:

*reverse code the appropriate items in pms
vreverse pms3, gen(pms3r)
vreverse pms5, gen(pms5r)
vreverse pms6, gen(pms6r)
vreverse pms8, gen(pms8r)
vreverse pms9, gen(pms9r)
vreverse pms11, gen(pms11r)
vreverse pms12, gen(pms12r)
vreverse pms13, gen(pms13r)
vreverse pms14, gen(pms14r)
vreverse pms22, gen(pms22r)
vreverse pms23, gen(pms23r)
vreverse pms24, gen(pms24r)
*recode appropriate items in diri
vreverse diri3, gen(diri3r)
vreverse diri4, gen(diri4r)
vreverse diri7, gen(diri7r)
vreverse diri12, gen(diri12r)
vreverse diri13, gen(diri13r)
vreverse diri14, gen(diri14r)
vreverse diri15, gen(diri15r)
vreverse diri18, gen(diri18r)
vreverse diri19, gen(diri19r)
*now summate the rating scales

gen 
pmsscore=pms1+pms2+pms3r+pms4+pms5r+pms6r+pms7+pms8r+pms9r+pms10+pms11r+pms12r+pms13r+pms14r+pms15+pms16+pms17+pms18+pms19+pms20+pms21+pms22r+pms23r+pms24r+pms25

gen 
diriscore=diri1+diri2+diri3r+diri4r+diri5+diri6+diri7r+diri8+diri9+diri10+diri11+diri12r+diri13r+diri14r+diri15r+diri16+diri17+diri18r+diri19r+diri20+diri21+diri22+diri23+diri24+diri25+diri26+diri27+diri28

The do file runs in stata as far as generating the pmsscore.  Then it 
stops with an "end of do file" message.  diriscore never gets generated.

But if I then copy and past that last command, with gen diriscore= et 
cetera, into the command window of stata, it works fine, generating 
diriscore.

A separate do file, containing just that last command, when called after 
the original do file is run, does nothing.

I am puzzled, as usual.

Any suggestions?

Thanks.
