-ylx
: Maximum length of expressions that can be expanded with the post-increment operators of FORTRAN or RATFOR
FORTRAN and RATFOR can expand expressions such as x(i) +=
dx
into their FORTRAN counterparts such as x(i) = x(i) + dx
.
It does so in a very straightforward way, by copying the expression to
the left of the equals sign. -ylx
controls the maximum size of
that expression.
