! The tests. Each call to a show_* function must have a unique set

!
! If a show_* line ends with VARS=... where '...' is a comma
! separated list of variable names, these variables are assumed to
! be part of the call line, and will be expanded by the test script,
! for example:
!
! do x=1,9,1
! do y=x,10,1
! call show_1d (some_array (x,y)) ! VARS=x,y

! In this example the test script will automatically expand 'x' and
! 'y' in order to better test different aspects of GDB. Do take
! care, the expansion is not very "smart", so try to avoid clashing
! with other text on the line, in the example above, avoid variables
