TVG - TEKTRONIX VIEWGRAPH GENERATOR TVG is an interactive program used to produce text-only viewgraphs. Currently it can only be used on the TEK 4014. TVG is initiated by typing TVG in response to the MCR prompt: >TVG . To obtain more information on TVG enter: HELP TVG subqualifier where subqualifier is one of the following: CHAR-SETS DEFAULTS COMMANDS SUBCOMMANDS COPY SWITCHES For complete documentation (including a sample of the different character sets) contact the Distributed Systems Group. 2 CHAR-SETS TVG Hershey Character Sets SET CHARACTER SET TYPE SET CHARACTER SET TYPE 3 Simplex Roman 13 Complex Script 4 Simplex Greek 14 Gothic Italian 5 Duplex Roman 15 Gothic German 6 Complex Roman 16 Cyrillic 7 Complex Greek 17 Triplex Roman 8 Complex Italic 18 Triplex Italic 10 (M) Math and special characters 20 Miscellaneous characters 11 (G) Gothic English 30-37 Chinese 12 (W) Simplex Script 38-39 Japanese 2 COMMANDS F/ollowing is a list of TVG commands: BYE Logs you out of TVG, same as ^Z . CLEAR Clears all text and box definitions; default value is unchanged. Et Enter new text to be associated with the next avialable identifier. (No spaces between E and the first text character.) F [n] Plot final viewgraph on TTn:. Hit RETURN key to return to TVG command mode. MA [l] d Modify the alignment of textl to d, where d=R right justifies textl, d=L left justifies textl and d=C center textl. MB l Draw up to 32 connected line segments. MC [l] n Modify the character set of textl to n. MO [l] d Modify the orientation of textl to d degrees. MP l Modify the position of textl to that of the crosshair input. The alignment can be chosen by typing L, C or R to set point. MS [l] d Modify the size of textl to d inches. MT l t Replace textl with new text t. N n Place n ticks on right side during REDRAW. R Redraw with identifiers. S t Save as file named t U t Unsave (recall) from file named t. 2 DEFAULTS TVG DEFAULTS TVG Assumes the following defaults: MA = C ! Centers Text MC = 3 ! Simplex Roman MO = 0. ! Orientation is 0 degrees MS = .25 ! Text size is .25 inches Note: On the commands MA, MC, MO and MS, if no textl is specified, the default value is changed for subsequent text entered. When using the save and unsave commands .TVG is the default file type. 2 COPY #SWITCHES 2 SWITCHES To generate a final viewgraph and copy, type: >TVG filename.ext/switches or >TVG @commandfile Where "filename.ext" is the name of the file in which the viewgraph description is saved, and "switches" are optional switches to control the output format of the final viewgraph. Possible switches are are: /-FI Suppress the filename identifier at the bottom right of the viewgraph. /MG:n.nn Specify magnification factor for the viewgraph. /TE:n Specify final viewgraph output to terminal TTn: . 2 SUBCOMMANDS TVG Subcommands can be used to modify a text line. They are preceded by a dollar sign ($) and inserted in the text line where the action is to take place. Following is a partial list of the subcommands available: D Shift down to first level of subscript. E Shift to exponent level. L Shift down to second level subscript. M Change to math character set. N Shift to normal level. W Change to script character set. X Return to entry character set. n Change to character set n=3,4,...,29. - Underline between occurences, ("$-...$-"). = Double underline between occurences, ("$=...$="). For example: E This $Wpart of the line is in script and $-underlined. For more information see the documentation distributed by the CAT group.
