O.K. here are my complete routine with the const arrays declarations
(It is a 7seg-decoder for a 4-digits display)

the disfunctionating code is in /*... */

void makeinfotxt(char z)

{ char a, e, c , d;
/*
glta=nrseg[Seg7txt[z][0]];
glhu=nrseg[Seg7txt[z][1]];
glze=nrseg[Seg7txt[z][2]];
glei=nrseg[Seg7txt[z][3]];
*/

a=Seg7txt[z][0];
e=Seg7txt[z][1];
c=Seg7txt[z][2];
d=Seg7txt[z][3];

glta=nrseg[a];
glhu=nrseg[e];
glze=nrseg[c];
glei=nrseg[d];

}

const char code nrseg[36]=
{
/*0*/ 136, /*1*/ 187, /*2*/ 148, /*3*/ 146,
