Table 6: ISO Latin 1 Character Set • "\a" (ASCII code 7) Beep: produces an audible or visible alert. The position of the next character is not to be changed. • "\b" (ASCII code 8) Backspace: goes one character back and continues drawing there. • "\f" (ASCII code 12) Formfeed: is used in combination with an additional parameter to change the current form of output. – "\fu" (ASCII codes 12 117) starts underlining. – "\fI" (ASCII codes 12 73) starts italics typeface. – "\fb" (ASCII codes 12 98) starts bold typeface. – "\fB" (ASCII codes 12 66) starts very bold typeface. – "\fn" (ASCII codes 12 110) stops underlining, italics and bold typefaces, i. e. returns to normal typeface. 110
– Selecting special characters Special characters (all characters of the ISO Latin 1 character set) can be chosen from table 6 and specified as described there. For example: ∗ "\fi000" (ASCII codes 12 105 48 48 48) prints the ISO character 0. ∗ "\fi223" (ASCII codes 12 105 50 50 51) prints the ISO character 223 (the German ß). ∗ "\fi252" (ASCII codes 12 105 50 53 50) prints the ISO character 252 (the German ü). – Changing of current color for drawing characters The formfeed character followed by two digits signifying the color chosen from table 1 changes the color for the characters following in a string, thus enabling the first 100 colors of the map to be accessed. Example: 5.14 Remarks ∗ "\f00" (ASCII codes 12 48 48) sets the color to white ∗ "\f31" (ASCII codes 12 51 49) sets the color to black All titles of graphs and nodes have to be unique. A node can only have two near edges. If more than two near edges are specified for a node, the remaining near edges are converted into normal edges. A node with anchored edges can only have one near edge at maximum. Further, if anchored edges occur, the orientation is always top_to_bottom. The level of nodes (also of summary nodes) is not recognized unless the whole graph is drawn automatically, menaing unless at least one node has no specified location. Normally, all level 0 nodes form the uppermost layer, with nodes of other levels forming the next layer underneath. The level specification may conflict with a near edge specification, because the source and target node of a near edge have to have the same level. In this case, the level specification of the source or target node of the near edge is ignored. 111
