Editing Graphic character (section)

==ISO/IEC 646==
In ISO 646, graphic characters are contained in rows 2 through 7 of the [[code]] table. However, two of the characters in these rows, namely the [[space character]] SP at row 2 column 0 and the [[delete character]]&nbsp;DEL (also called the rubout character) at row 7 column 15, require special mention.

The space is considered to be ''both'' a graphic character and a control character in ISO 646.<ref>{{cite book|author1=L.R. Henderson|author2=A.M.

The delete character is strictly a control character, not a graphic character. This is true not only in ISO 646, but also in all related{{clarify|date=February 2012}} standards including Unicode. However, many other character sets deviate from ISO 646, and as a result a graphic character might{{efn|as is the case in [[code page 437]] and related standards}} occupy the position originally reserved for the delete character.{{efn|This does not mean the delete character is absent; it just means 0x7F is overloaded, and outputting it will either print the graphical character or perform a deletion, depending on the routine used. For example in most [[BASIC]] implementations, using the [[PRINT (BASIC)|PRINT]] command with 0x7F will delete, but using [[POKE (BASIC)|POKE]] will output the graphical character.}}
