{if (/^\*/) ## search for pattern starting with asterisk , that i found no where so what is the purpose. ? <-- look into spec for input.txt
{TFN = substr ($0,2) ## for all fields starting 2 characters will be assigned to variable TFN <-- just for the line with the leading *; shortcut for substr ($0, 2, rest of $0) := filename to which comparison is to be applied
SAM[TFN] = "-" ## Associative array would be declared and assiged value "-" to them. <-- Yes, as a starting point; additional elements to be added
SAM[TFN] = SAM[TFN] $0 "-" ## if the IF block become false then add "-" after each record. <-- concatenate the fields into SAM separated by "-"

Rest all going over head.
