C SUBPROGRAM:    mova2i      Moves a bit string from a char*1 to int

C ABSTRACT: This Function copies a bit string from a Character*1 variable
C   to an integer variable.  It is intended to replace the Fortran Intrinsic
C   Function ICHAR, which only supports 0 <= ICHAR(a) <= 127 on the
C   IBM SP.  If "a" is greater than 127 in the collating sequence,
C   ICHAR(a) does not return the expected bit value.
C   This function can be used for all values 0 <= ICHAR(a) <= 255.
