This is what -infix- is all about.

Alternatively, I'd consider reading this in as a string variable.

Let's suppose that there are blocks of 20 lines each.

infile str40 mystr
replace mystr = trim(mystr)
compress
egen block = seq(), block(20)
egen line = seq(), to(20)
reshape wide mystr, i(block) j(line)
destring mystr*, replace
