Ox 6: new features and fixes

New features and enhancements in version 6.0
Fixed problems in version 6.0

The Ox version number is kept in line with the OxMetrics fron-end version. Otherwise, not much has changed in this version of Ox.

New features and enhancements in version 6.0

• Added QQ_N_SE for DrawQQ: pointwise asymptotic Std.Error bands on normal QQ-plots.
• Recession shading line style (style constant is ST_SHADING; shading is on when the variable has value 1, off otherwise).
• oxdraw.h: defining ST_
• Introduced oxo version (separate from Ox version), current version is 5 (unchanged from Ox 5 to Ox 6). When the oxo version changes, .oxo files must be recompiled.

Fixed problems in version 6.0:

• OxPack: fixed potential issue in "OxPackSpecialDialog"("OP_VARIABLE",...
• Repeatedly running an Ox file that saves a graph could result in multiple instances of the same graphics files being open in OxMetrics (asking for a reload every time it changes).
• The following code would leak memory: fn() { decl logdet = rann(100000, 100); invertsym(2 * unit(2), &logdet); } Because invertsym wouldn't free before assigning. This applies to a few library functions that return an integer or double through an argument (and was only likely if a variable was reused).
• PcFiml class lacked GetResVar() (virtual from Modelbase)
• DrawAdjust doesn't work for DrawDensity because the title is drawn after the density.
• MaxSQP(F): didn't return MAX_MAXIT if max reached; rounding errors on Hi/Low bounds could push parameters outside bounds by a tiny bit.
