Peter MapBasic's Line Input # statement recognizes the ASCII CR character as and end-of-line indicator, whether or not the following character is an ASCII LF.
Therefore you cannot develop a MapBasic program to read text lines that include embedded CR characters. Your only solution is to pre-process the text file using a text editor or a custom program that supports character-at-a-time input and replace any embedded CR characters with another character in the range Chr(32)..Chr(255) such as Chr(124)="|" . For example, I once developed a Delphi program called FIXCR that performs this task. FIXCR used the Delphi BlockRead() procedure to read the input 1000 characters at a time and the WriteLn() procedure to write the output one line at a time, fixing embedded CRs as it went.
