IARGC()
Description
Get the number of arguments passed to the program.
Class
Elemental nonstandard function.
Result type
Integer.
Result value
If no arguments are passed to the program, IARGC returns zero. Otherwise IARGC returns a
count of the arguments that follow the program name on the command line.
IBCLR(I, POS)
Description
Clears a bit to zero.
Class
Elemental function.
Arguments
I must be of type integer.
POS must be of type integer. It must be nonnegative and less than BIT_SIZE(I).
Result type/
type parameters
Same as I.
Result value
The result has the value of the sequence of bits of I, except that bit POS of I is set to zero. The
model for the interpretation of an integer value as a sequence of bits is in “The Bit Model” on
page 508.
