The AXIS'137 routines perform manipulations specific to Asterix axis structures and data.
The first five of these routines use the AXIS LABELs in a binned dataset to obtain the index number (for use in BDA'137 routines) of an axis with a particular label.
If the specified axis is found, then AXDIM (or X_AXIS, Y_AXIS, T_AXIS) is set to the index number of that axis. If no matches are found, then a value of 0 is returned. If N matches are made (N > 1), then a value of -N is returned.
The new routines are:- N.B. arguments to the left of the ';' are imports and to the right are exports.
