Parse1DExpr
Example:
/* Assume i is the EStackIndex of the tagged floating-point number 314.15926535898
and that the current MODE setting for Display Digits is FLOAT 6, then */
HANDLE h;
h = Parse1DExpr (i, TRUE, 4);
/* returns a HANDLE to a memory block containing width restricted ASCII text 314. */
h = display_statements (i, TRUE, 3);
/* returns a HANDLE to a memory block containing the width restricted ASCII
text . . . , because the number cannot be represented in 3 characters. */
