BLOCK

BLOCK defines how the following numeric data block shall be interpreted. The definitions of X and Y coordinates may also be expressed as a function of the column values, making it possible to perform transformations.

Syntax

BLOCK X&=C#; ...; Y&=C#; ...; GOC=C#,@@@...

 

&’ are optional unsigned integers that make it possible to plot several (maximum 9) X- or Y- axis columns. #’ are unsigned integers identifying the column numbers. The column number # in “GOC=C#” is the location of any possible GOC codes in the current data BLOCK; @@@ stands for the default Graphical Operation Code (GOC) for the current BLOCK. The GOC code inside the current table is only necessary if the current default GOC is not applicable.

The GOC is a combination of the following characters:

Character Meaning

W, V or N

To use world (W), virtual (V) or normalized (N) coordinates. W is the default.

A or R

XY are absolute (A) or relative (R) values. A is the default.

M or D

To perform a move (M) or draw (D) operation to XY. M is the default.
B

To apply “soft” splines on a line drawn between the coordinate pairs (used only on BLOCK data).
S

To plot default symbol at XY.
S#

To change default symbol to No # symbol and plot it at XY.
‘TEXT

To plot TEXT at XY. It must be the last operation in a GOC code. The TEXT following the ’ command is interpreted and expanded by the DIGLIB software, if it includes any ^ operator or STRING names using the ~ descriptor.
