i'm not sure what ver of pbp you are using but

@ Device Pic16F630,HS_osc, wdt_off, pwrt_on,protect_off, mclr_off

is old stuff, and probably case sensitive HS_osc looks doubtful
if this line is incorrect then the actual config fuse you are setting is the pbp default not what you think.
the default will be most likely use a 4mhz clock

With "DEFINE OSC 16", PAUSE 200 gives a delay of 50 msec
means the osc is 4mhz not 16, so your config line is incorrect

The resolution here is therefore 250µsec per "unit".
pause is always in mS but the actual osc must march the defined OSC

What are legacy commands, I don't know this term
commands that resemble old basicstamp style commands ,they are not as well integrated in the pbp operating environment
