debug session breaks because error.

hier is my user-defined command:

set $myvar = 0

define run
    if $myvar
        printf "\n 000000000000000000000000000 \n"
        disable
       
        printf "\n 44444444444444444444444444444 \n"
       
        k
        set remotebaud 300
        target remote /dev/ttyS3
        load reset.elf
        symbol-file reset.elf
        # set breakpoint to reset vector
        b * 0

        printf "\n 555555555555555555555555555555 \n"

        # start program
        c
        delete * 0
       
        printf "\n 666666666666666666666666666666 \n"
       
        # kill program
        k

        printf "\n 222222222222222222222222222 \n"

        set remotebaud 300
        target remote /dev/ttyS3
        load init.elf
        symbol-file init.elf
        # set breakpoint to end of program
        b end_init
        # start program
        c
        # delete all breakpoints (werden nicht mehr benutzt)
        clear end_init
        #kill program
        k
       
        printf "\n 33333333333333333333333333333 \n"
       
        set remotebaud 300
        target remote /dev/ttyS3
        load sample.elf
        symbol-file sample.elf
        set $myvar = 1
        enable
        continue
    else
        set $myvar = 1
        printf "\n 111111111111111111111111111 \n"
        continue
    end
