How to check the content in a text file line

[santoshmvs]

hi all,

i had the following problem:

• There is a text file with multiple lines of data in it
• The data comprises of characters, numbers and symbols
• In this file, any line can be commented (till the end) by using symbol ';'(semi-colon)
• Now i have to find the number of occurences of a symbol '$' in this data, such that
• it should not exist in a commented line
• One more limitation is that ';' (semi-colon) could occur at any position in a line, i.e., if this occured in the middle of the line, then all the following data in the line is taken to be as commented one and we have to skip it and move to next line.

Plz do help.

Regards,

santosh

Can you post an example of the text file?

thanks

Hi santosh,
just a guess this is what you need.

hi david,

i think the following attachemnt will be sufficient:

i have to calculate the number of '$' in the file, excluding those which are preceded by ';' in the same line

Thanks Santosh

You should try coding up Dave's suggested solution and let Dave know that it works for you and provide him with lots of stars

cheers

hi dave,

Thanks for ur reply,

the code which u gave works perfectly at all the conditions given in the problem,

except that when this semi-colon ';' comes in the middle of the line,

then we have to skip the data following it (semi-colon) in the line and count the number of occurences of '$' precedding ';' ,

i think here we face a problem.

Plz do reply.

Regards,

santosh.

Yes, I found a (for me) very common mistake, there must the "<>0" be replaced by a ">=0", then it works. David Cramers solution is very good, when you expect only one $ in a line.

Sorry,
I have only 8.0 on this computer, so I can only make 7.1- VIs. Perhaps it helps...
