    .include "telestrat.inc"

    lda   #$01 ; Mode 0
    BRK_TELEMON XMAINARGS

    sta ptr_cmd
    sty ptr_cmd+1 ; ptr_cmd contains the ptr to the command line. It allocates a string, it needs to be free when the program does not need it anymore

See initmainargs macro from orix-sdk to use it

XMAINARGS allocates a chunk in memory, it must be free at the end of the use of the parameters
