Numbers of Records
The exact number of records that can be stored in a data table is governed by a
complex set of rules, the summary of which can be found in the appendix
Numbers of Records in Data Tables
(p. 466).
7.8.4.10.2 Declaring Subroutines
Read More See section Subroutines
(p. 288)
for more information on programming
with subroutines.
Subroutines allow a section of code to be called by multiple processes in the main
body of a program. Subroutines are defined before the main program body of a
program.
Note
A particular subroutine can be called by multiple program sequences
simultaneously. To preserve measurement and processing integrity, the CR1000
queues calls on the subroutine, allowing only one call to be processed at a time in
the order calls are received. This may cause unexpected pauses in the conflicting
program sequences.
7.8.4.10.3 'Include' File
An alternative to a subroutine is an 'include' file. An 'include' file is a CRBasic
program file that resides on the CR1000 CPU: drive and compiles as an insert to
the CRBasic program. It may also run on its own
(p. 116).
It is essentially a
subroutine stored in a file separate from the main program file. It can be used
once or multiple times by the main program, and by multiple programs. The file
begins with the SlowSequence instruction and can contain any code.
Procedure to use the "Include File":
1. Write the file, beginning with the
SlowSequence instruction followed by any
other code.
