APPENDIX B — SCS/DCA COMMAND SUMMARY | Page | |
|
|
|
Command: | Set Line Density (SLD) |
|
Format: | 2B C6 nn ld |
|
Printers: | 3812, 4214, 5219, 5224, 5225 |
|
Action: | Sets the height of one line of print to be the value of the | |
| ld parameter divided by 72 inches. |
|
| For the 4214, if the value of the ld parameter is greater | |
| than 48h, a default value of 0Ch (6 lines per inch) will be | |
| used. |
|
| For the 5219, ld parameter values other than 12h (4 lines | |
| per inch), 0Eh (5.33 lines per inch), 0Ch (6 lines per | |
| inch), 09h (8 lines per inch), 08h (9 lines per inch) and | |
| 06h (12 lines per inch) will result in no operation; line | |
| density remains unchanged. |
|
| For the 3812, 5224 and 5225, all values of the ld | |
| parameter are allowed. |
|
| For the 3812, Computer Output Reduction (COR) mode | |
| causes the ld parameter to be reduced automatically to | |
| 70% of its set value (the CORVER%= option default | |
| value). This reduces a form height of 11 inches to 7.7 | |
| inches. |
|
IBMEMUL: | Same as the 3812. |
|
| Because many target printers are not capable of changing | |
| line density (line density is a function of the font | |
| selected), the OPTIMA does not send line feeds to most | |
| printers. Instead, it performs vertical downward | |
| movements (with the PFS VERMOVE>) to simulate IBM | |
| line spacing and to provide full support for this | |
| command. |
|
| If the Initial Condition Set specified by Set Initial | |
| Conditions (SIC) is Data Processing (DP), the line | |
| density set either by this command or by the Set Single | |
| Line Distance (SSLD) command is used in page length | |
| calculations when determining orientation automatically. | |
275EMUL: | No effect, except that if the vv parameter is less than 0Ch | |
| (6 lines per inch), subsequent lines are double spaced. | |
