Strange error from DrawFile_Render

When rendering a skewed JPEG, I get the following successive errors from the SYS “DrawFile_Render” command at line 2760:

‘System variable SCSI$Path not found at line 2760’
followed by
‘Transformed JPEG plotting is not supported by this version of the SpriteExtend module at line 2760.’
Both versions 1.81 and 1.84 of the SpriteExtend module behave like this.

Another strange error from DrawFile_Render occurs if you try to render a Draw file with an unknown font.

You get the error ‘(Number)’ which is error number &16B from OS_EvaluateExpression.

You do not get this error if you load the Draw file into !Draw – the unknown font is rendered as System font.

If you load the Draw file into memory and use DrawFile_Render to render it, it renders it using the system font and then produces the error &16B ‘(Number)’.

Surely DrawFile_Render should not produce an error for an unrecognised font?
