reading a real number from a character variable

[nandita]

I'm using the following code:

character(10) text

real(4) num

...

read(text,*) num

It works fine when I assign a value to 'text' manually.

However, when Iassign a value to 'text' using GetDlgItemText and then try to read it into 'num',I get a this run-time error:

forrtl: severe(59): list-directed I/O syntax error, unit -5, file Internal List-Directed Read

What could the problem be?

Two things. Using list-directed formatting for this purpose is dangerous, as it will accept things you may not, such as "Twinkie". Try it. Consider using G format instead.

Second, Win32 routines return null-terminated strings. Use INDEX to find the NULL and get the substring of the actiual text.
