*     Author  : S. Pellerin ARMA/AES Avril 2000
*     Revision:
*
*     JM Belanger CMDA/SMC  Aug 2000 
*                   . 32 bits conversion 
*
**    Purpose: scalar horizontal interpolation
*
*
*Arguments
*    input:
*          psrcvar(kscol,klev) : source variable
*          kscol               : number of collumns of source variable
*          ksrcgid             : grid id of source variable
*          ktcol               : number of collumns of target variable
*          ktrggid             : grid id of target variable
*          klev                : number of horizontal slabs to interpolate
*          cddegint            : degree of horizontal interpolation
*    ouput:
*          ptrgvar(ktcol,klev) : target variable
