Reading a text file line-by-line or blockwise with a progress indicator

You can use 'InStr' to check if the line read from the file contains a
certain string.

Greetings, I need to read (unformatted text) from stdin up to EOF into a char buffer; of course I cannot allocate my buffer until I know how much text is available, and I do not know how much text is available until I have read it... which seems to imply that multiple reads of the input stream will be inevitable. Now I can correctly find the number of characters available by: |

Cheerio, I would appreciate opinions on the following: Given the task to read a _complete_ text file into a string: What is the "best" way to do it? Handling the buffer is not the problem -- the character input is a different matter, at least if I want to remain within the bounds of the standard library.
