9.204 MVBITS — Move bits from one integer to another

Description:

Moves LEN bits from positions FROMPOS through FROMPOS+LEN-1 of FROM to positions TOPOS through TOPOS+LEN-1 of TO. The portion of argument TO not affected by the movement of bits is unchanged. The values of FROMPOS+LEN-1 and TOPOS+LEN-1 must be less than BIT_SIZE(FROM).

Standard:

Fortran 95 and later, has overloads that are GNU extensions

Class:

Elemental subroutine

Syntax:

CALL MVBITS(FROM, FROMPOS, LEN, TO, TOPOS)

Arguments:

FROM	The type shall be INTEGER.
FROMPOS	The type shall be INTEGER.
LEN	The type shall be INTEGER.
TO	The type shall be INTEGER, of the same kind as FROM.
TOPOS	The type shall be INTEGER.

Specific names:

Name	Argument	Return type	Standard
MVBITS(A)	INTEGER A	INTEGER	Fortran 95 and later
BMVBITS(A)	INTEGER(1) A	INTEGER(1)	GNU extension
IMVBITS(A)	INTEGER(2) A	INTEGER(2)	GNU extension
JMVBITS(A)	INTEGER(4) A	INTEGER(4)	GNU extension
KMVBITS(A)	INTEGER(8) A	INTEGER(8)	GNU extension
