Function: GDSBOX

Purpose: GDSBOX prompts the user to define a box inside/around a
subset.

Category: USER IO, PHYSICAL COORDINATES

File: gdsbox.c

Author: K.G. Begeman

Use: CALL GDSBOX( BLO , In/Output integer array
BHI , In/Output integer array
SET , Input character*(*)
SUBSET , Input integer
DEFAULT , Input integer
KEYWORD , In/Output character*(*)
MESSAGE , Input character*(*)
SHOWDEV , Input integer
OPTION ) Input integer

BLO On input this array may contain the default
centre or the default lower left edge of the
box (depends on OPTION).
On output it contains the user defined lower
left grid coordinates of the box.
BHI On input this array may contain the default
size or the default upper right edge of the
box (depends on OPTION).
On output it contains the user defined upper
right grid coordinates of the box.
SET Name of set for which a box should be defined.
SUBSET Coordinate word of the subset for which a box
should be defined.
DEFAULT Default code as in USERxxx.
KEYWORD Keyword prompts the user to enter a box. If
KEYWORD is blank the GDSBOX will prompt with 'BOX='.
MESS Message for the user. If MESS is blank then
GDSBOX will generate its own message.
SHOWDEV Device (as in ANYOUT) to which some info
about the chosen box is displayed.
OPTION The different options are:
1 box may exceed subset size
2 default is in BLO
4 default is in BHI
8 box restricted to size defined in BHI
16 return immediately in case of errors
These codes work additive. So when OPTION = 0
or 1 then the default is entire subset.
If option 16 is set, then in case of errors this
argument will be set to -1 and GDSBOX will return
immediately.

Description: GDSBOX is a subroutine which prompts the user to enter a
box around/inside a subset.
It always follows upon a call to GDSINP. The input syntax
is described in document dcdpos.dc3.
