C Edit history:
C 32 fix bug in APISLB that caused overscaling of values
C 33 alter calling sequences for ATOLSQ, ATOLSP so that turning off
C least squares can be done by eg CALL ATOLSQ(-1)
C 34 COMMON /APFIX/ ommitted in APPCHK - add it
C 35 remove basic plotting routines from APLOT.FOR to
C a new file APSUB.FOR, so that they are easier to modify.
C 36 Fix bug in APPSEX that caused title exponeents to be written
C using the plot title size instead of the axis title size.
C 37 Fix a bug in ATOPRM that caused bad range checking on
C parameters 13, 14 and 17
C 40 COMMON /APFIX/ ommitted in ATOCHL - add it
C 41 Add a new ATOPRM #45 - tick spacing for Y axis
C ATOPRM #10 becomes tick spacing for X axis
C 42 Check lengths of titles and don't plot if zero
C Don't draw a notes box if no notes
C 43 Plot tick values before axis titles so that title exponent
C can be plotted immediately following title
C 44 Alter frame and tick drawing so that pen movements are
C minimised - handy for pen plotters
C 45 Add minor version numbers and revise version number plotting
C 46 Up maximum number of character labels to 24 so that it can
C handle hours of the day
C 47 Further change the box and tick drawing algorithm so that
C if shading is specified for ticks, the ticks are drawn in
C a seperate pass to allow for a single pern change
