MVBITS — Move bits from one integer to another#

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

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).

Parameters

  • 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.
