Who knew that a syntax error could totally make my day

WARNING: GEEK CONTENT ALERT

So I'm working in Stata, the statistical analysis software we use here in the office. I know I need to run a "do" file from within the program, but I can't remember the exact syntax, so I give it a shot.

Here's what I typed in:
m:\ccr\data\ccrupdate.do 21

Here was Stata's response:
'do' found where almost anything else expected

Good to know the folks at Stata have a sense of humor...
