Replaces a global JavaScript with a new one.
The parameter Index must be a valid handle of a global JavaScript. The parameter NewScript must be a valid JavaScript. The script is not checked by DynaPDF whether it is valid or not. Note that older Acrobat versions do not support all JavaScript functions. Due to several bugs in certain Acrobat versions invalid scripts can cause access violations in Adobe's Acrobat. Test your scripts carefully with all Acrobat versions which must be supported.
