Software

To solve this problem, SIMPL+ has introduced the concept of function libraries.

Simply put, a function library is a collection of user-defined functions placed in a

separate file. A library can consist of only a single function, or can consist of every

function you have ever written. More likely, you will organize your libraries so that

each one contains related functions. For example, you may create a "string handling"

library, which consists of a number of functions that perform useful operations on

stings.

Once a function has been included inside of a function library, it now becomes

accessible to all SIMPL+ modules that are made aware of it. To make a SIMPL+

program aware of a particular library, you must use the #USER_LIBRARY. To

include a user library within a SIMPL+ module, the syntax is as follows:

#USER_LIBRARY "MyStringFunctionLib"

Note that the file extension (.usl in this case) is left out. The above example refers to

the function library called "MyStringFunctionLib.usl." Any number of user libraries

can be included within a SIMPL+ module.

Special function libraries that are created by Crestron and made available to all

customers can be used in a similar manner. The only difference is the use of the

#CRESTRON_LIBRARY compiler directive in place of #USER_LIBRARY.

Crestron function library files end with the extension .csl.

Compact Flash Functions

The 2-series control system supports reading and writing to compact flash cards.

Certain control systems have a built-in compact flash slot with the ability to easily

insert and remove compact flash cards (i.e., AV2, PRO2, and PAC2).

Data storage is a valuable, powerful and important part of programming. The ability

to store and retrieve data from a removable data source can provide many useful and

powerful solutions. Some of these solutions include the ability to backup data,

transferring data from one control system to another, reading and writing data to and

from formats that other database programs can recognize, and implementing

database-driven programs (the ability for a program to act dynamically based on

actions defined in the database).

The SIMPL+ file functions perform file access with the control system’s compact

flash card. Because of the overhead involved with maintaining current directory and

file positions, there are restrictions on file I/O. Each SIMPL+ thread (main loop or

event handler) that requires file operations must first identify itself with the operating

system. This is done with the function, StartFileOperations. Before terminating the

thread, the function, EndFileOperations must be called. Files cannot be opened

across threads. In other words, you cannot open a file in one thread, such as Function

Main, and then access the file with the returned file handle in another thread, such as

an event handler. Files should be opened, accessed and closed within the same

thread.

CheckForDisk and WaitForNewDisk

Before accessing compact flash, the program must either first check to see if a

compact flash card exists within the control system, or wait for a card to be inserted.

Certain programs might rely on the compact flash card being inserted within the

control system. The function, CheckForDisk, will test for the existence of a compact
