ZI-data too big

Hi,

I have the following BIG structure:

typedef struct
{
        BYTE c_re[3];
        int c_gnrl;
        float c_time[2];

        BYTE c_cmm[13];
        int c_cmm_p[2];

        BYTE c_ext[10];
        int c_ext_p[10];

        int c_stp[50][3];

        int m_gnrl[100][10];

        float m[100][22];

        float m_e[100][22];
        float s_clb_[10];

        int an[100][22];

}pthm;

pthm test;

void main()
{
 test.an[0][0]
}

The problem is quite obvious, its too big.
How can I make sure it doesn't consume the ZI-data memory?

kind regards,
Wim
