fortran read statement 2

[nouraaa]

i didn't get what does read statement do in this case?:

int x
read(textpart(2*i-1),'(f20.0)',iostat=istat) x

textprat is an array of char*
istat is an integer

anyone could help please?

the first parameter shouldn't be an integer???

have you read the documentation for "READ"? It should all be explained there.

Basically, the first argument is the place you read from...be it a unit number (file) or a character string.

The second argument is the format you expect the data to be in. Typically, it is best to stay away from any specific format and simply read in a 'list directed' fashion.

The iostat flag sets the variable you pass to give you feedback on the exit status of the READ operation.

The 'x' following the "READ(...)" is the variable whose value you are trying to read.

someone could recommend a good documentation for FORTRAN, it's my first experience with this language and i didn't find anything interesting (or i'm not a good searcher) .
thanks.
