Interrupting SHELXL93

Interrupting SHELXL93 under WinGX


Two mechanisms are provided for interaction with a SHELXL93 job which is already running under WinGX.

If the button on the tool bar or the ESC key is pressed during least-squares refinement, the program completes the current cycle and then, instead of further refinement cycles, continues with the final structure-factor calculation, tables and Fourier etc.

Otherwise or ESC has no effect.

If the Cntl-C or Cntl-I keys are pressed the program halts immediately
