PASRUNOPTS
PASRUNOPTS is a new Pascal runtime variable that determines how
the runtime library processes floating-point number string format. This
variable can be used to increase the portability of PASCAL to other
languages and vendors.
Description
The table for this variable (see Table 1-5) is divided into three columns;
currently only column 1 is supported. The value specified in column 1
determines what exponent is printed for LONGREAL output. It also
selects what exponent is valid for LONGREAL and REAL input.
Exponent Values
Table 1-5 Exponent Values
NOTE The way the compiler recognizes its constants is not affected (i.e., only
"L" is valid for LONGREAL).
