'''GROB''' is a raster graphics format associated with HP-48 and HP-49 series calculators.

There are at least two ways to encode a GROB image: "binary" and "ASCII". There may also be a third encoding called "text" or "ASC".

== Identification ==
A binary GROB file begins with "HPHP48" or "HPHP49", and has bytes <code>1E 2B</code> at offset 8.

ASCII format apparently begins with "<code>GROB </code>"

+'''GROB''' is a (usually) bi-level raster graphics format associated with HP-48 and HP-49 series calculators.
 There are two ways to encode a GROB image: "binary" and "ASCII". Sometimes, GROB images are also [[ASCII Encoded HP 48 Object|ASC-encoded]].
-== Format ==
+== Format details ==
 Binary format has an 18-byte header, followed by the pixel data.
 == Identification ==
-A binary GROB file begins with "<code>HPHP48</code>" or "<code>HPHP49</code>", and has bytes <code>1E 2B</code> at offset 8.
+A binary GROB file begins with "{{magic|HPHP48}}" or "{{magic|HPHP49}}", and has bytes {{magic|1E 2B}} at offset 8.
-ASCII format apparently begins with "<code>GROB </code>". An ASCII GROB might be embedded inside a script, or preceded by a "<code>%%HP</code>" header line, so it won't necessarily start at the beginning of the file.
+ASCII format apparently begins with "{{magic|GROB }}". An ASCII GROB might be embedded inside a script, or preceded by a "{{magic|%%HP}}" header line, so it won't necessarily start at the beginning of the file.
