create_block_seq: Create a data block in the server with a simple linear...

In rjazz: Official Client for 'Jazz'

Description

Creates an (integer or real) data block in the server and stores it in the persistence with a simple linear sequence. The type of the block can later be changed to a compatible type: BLOCKTYPE_C_INTEGER to BLOCKTYPE_C_FACTOR or BLOCKTYPE_C_GRADE and BLOCKTYPE_C_REAL to BLOCKTYPE_C_TIMESEC by a later call to set_compatible_data_type().

Usage

create_block_seq(source, block_key, from, to, by = 1, host = .host.)

Arguments

source	The Jazz source. Jazz persistence is organized in sources. All sources except 'sys' and 'www' are user defined. Sources are 15 char long alphanumeric or underscore.
block_key	The key identifying the block. Keys are 15 alphanumeric or underscore characters. They can be user defined or created by new_key(). Also, meshes use block keys internally.
from	The starting value. A real number or an integer.
to	The end value, may not be included, it is the supremum or the infimum when 'by' is negative.
by	The increment. It may be negative, in that case 'from' must be bigger than 'to'.
host	(Optional) the name of the jazz server host (including the port). Usually set just once via set_jazz_host().

Value

TRUE or raises an error on failure.
