DCLPARA(1) GFD Dennou Club Library DCLPARA(1)

NAME

dclpara - display current values of DCL internal parameters

SYNOPSIS

dclpara [ group_name ]

DESCRIPTION

dclpara is a utility program included in the GFD Dennou Club Library (DCL). It prints the list of internal parameters and their current values for a specified DCL parameter group.

DCL manages its internal state (settings for graphics, layout, mathematical constants, etc.) through named parameters grouped by functionality. This command allows users to inspect these values at runtime.

If group_name is not provided as a command-line argument, the program will prompt for it interactively.

Supported Groups

The following 3-character group names are supported:

General Library Parameters (Misc, Math, etc.)
General Library Character Parameters (Character strings)
Simple Graphics Parameters (Primitive graphics settings)
Standard Window Parameters (Window system settings)
Standard Window Character Parameters
User Coordinate Parameters (U-Pack)
User Data Parameters (U-Pack 2D data processing)
User Explanation Parameters (U-Pack explanation axes)
User Grid Parameters (U-Pack grid generation)
User Layout Parameters (U-Pack layout handling)
User Map Parameters (U-Pack map projection)
User Scatter Parameters (U-Pack scatter plots)
User Z-coordinate Parameters (U-Pack Z-axis/Contour)

OPTIONS

dclpara accepts standard DCL runtime parameters.

EXAMPLES

To list parameters for the Simple Graphics (SGP) group:

$ dclpara SGP
BITMAP = 0
CLRMAP = 1
IWIDTH = 600
...

To check Map Projection (UMP) settings:

$ dclpara UMP
