String manipulation and parsing

[malladisk]

Hi!
Does VB support easy string manipulation? Specifically, I need to be able to read one character at a time from a file, so that I can parse the contents of the file. Is there a getc function?
Thanks,
Sashi

You need to do some research on instr(), mid(), left() and right(). These are VB's string manipulation functions.

Hope that helps,
Erica

You can use the Input function to read one character at a time from a file.

Do you really need to read ONE character at a time to parse a file? If the file is a text file, then you better have a look at my solution to a similar (but limited to the first word of a line) problem posted in thread222-109781.

The code can easily (?) be adapted to more complex parsing. _________________________________

rvBasic is correct, it is inefficient to read text files byte by byte. The concept needs to be:

Get it. (As much as you can)

Process it. (However you may)

You need to rember the relative speed of the parts of your system:

Define Memory access as 1.

(Hard) Disc Access is 1/10

(Floppy) Disc (Removable Nedia - in General) is 1/100
