Trying to code historical high price. Code worked in Stata 11, doesn't work in Stata 13.

by ticker: generate record = prc[1] if _n == 1
by ticker: replace record = record[_n-1] if prc <= record[_n-1]
by ticker: replace record = prc if prc > record[_n-1]

[Pasha Safarzadeh]

just figured it out...
by ticker: generate record = prc[1] if _n == 1
by ticker: replace record = max(record[_n-1],prc)
