Can someone tell me the operational difference between %s and %[A-Za-z]?? I have an instance where the first field in line of data is a capital letter. The %s identifier caused an error from the Scan form string vi. My vi is working but it would be helpful to know why one worked and the other did not. Thanks in advance.
Well, the direct answer to your question is in the Help file:
s—String (for example, abc). When scanning, s
matches only up to the next white-space character. A space matches one or more
consecutive white-space characters. To scan a string that may contain white
space, use the characters in set conversion code. Specify all the characters
which the string may contain within the brackets, including space or other
white-space characters.
[ ]—Characters in set. [
] matches a string that contains only the characters specified between
the brackets. Character matches are case sensitive. The [
] conversion code is useful only when you are scanning strings. To match
the caret symbol (^) in a set, make sure it is not
the first character after the bracket.
Thanks for the help. The difference is that the %s scans up to white space, My input is comma delimited without any white space. The %s scan, scanned until the first CR, which was 7 fields of data. Thanks again for the help.
