Transparency Mode H-1
H. DGCL
H.1 Datasouth Graphics Command Language
The Datasouth Graphics Command Language contains a powerful set of graphics and text
commands which can be accessible by the user from all emulation modes. The DGCL
structure consists of two distinct levels: a Transparency level (or mode) and a Task level. The
Transparency level can be accessed from any emulation mode by simply entering the up caret
PY command sequence (^PY). The Task level can be accessed from (and only from) the
Transparency mode by entering one of the Task initiation commands ^E, ^M, ^U or ^V.
The Datasouth Graphics Command Language will allow the user to:
• Draw variable length and variable width lines up to 13.2 inches horizontally by 13.2
inches vertically, with the line types solid, dashed, dotted, and dash-dotted, being user
selectable.
• Draw variable length and variable width boxes up to 13.2 inches horizontally by 13.2
inches vertically, with the box types solid, dashed, dotted, and dash-dotted, being user
selectable. The thickness of the horizontal and vertical line segments will also be
independently selectable.
• Print expanded characters in tenth inch increments up to 9.9 inches horizontally by 9.6
inches vertically. Horizontal and vertical dimensions can be controlled independently.
• Print variable height and variable ratio horizontal barcodes (up to 9.9 inches in height).
Human readable text will be user selectable. The most commonly used barcode symbols
will be supported.
• Customize DGCL entry and exit parameters via menu feature selection.
NOTE
The vertical tenth inch increment is only an
approximation and it is actually 7/72 inch.
Specifying a vertical dimension value of 99
yields an actual dimension of 9.6 inches.
