Fortran 77 Initialize Variables at Compile Time

[fastwink]

I need to force all variables to default to zero.
Some compilers have the option, but I have not found
this to be true for SUN Forte compiler. Is there
an easy way (maybe an option in the code)?

I have legacy source code and dread setting all variables to zero, but may have to do so.

You mean you want the opposite of -xcheck.

There isn't one as such. You can initialize the global ones (i.e. common blocks) in a block data segment. Everything else can be initialized with either /0/ after the variable name or in a DATA statement.

Yes - it is tedious. -xcheck will help you find the ones that have not been initialized.
