Re: st: tabout and foreach -counter error

Stata uses low-ASCII characters for right-single quote, left single
quote and double quote.

. di char(39)
'
. di char(96)
`
. di char(34)
"

I think these arguments for the -char()- function are invariant under
operating system, but I haven't checked.

Examples of correct usage in your code are

local heading = ""

 if `counter' > 0

Most of the other uses of quotation marks are incorrect.

Check out -asciiplot- (SSC) for a guide to -char()- on your system.
