Use this procedure to perform VAX IEEE floating-point conversion.

Syntax

---

ENVI_DOIT, 'VAX_IEEE_DOIT', /COPY_HEADER, IN_NAME=string, OFFSET=value, OUT_NAME=string

Keywords

---

COPY_HEADER

Set this keyword to specify that the header should be copied to the new output file.

IN_NAME

Use this keyword to specify an input filename for the VAX IEEE data.

OFFSET

Use this keyword to specify a byte offset to the start of the VAX IEEE floating-point data.

OUT_NAME

Use this keyword to specify a string with the output filename for the resulting data. If you set the keyword IN_MEMORY, you do not need to specify OUT_NAME.

  ; Initialize ENVI and send all errors

  ; and warnings to the file batch.txt

  ; Set the input VAX filename.

  out_name = 'testimg'

  ; Perform the VAX IEEE conversion.
