BCL Programmers Manual V2.00 (PDF) - Barix

3 BCL basics3.1 Starting with BCL3.1.1 Simple programHere is a simple program to test that tokenizer, tftp uploading, BCL interpreter in the BCL device andsyslog daemon 1 are all working well:SYSLOG "Hi, everything is OK"ENDAfter the program is uploaded to the device and interpreted, messages similar to thefollowing should appear in the syslog:Dec 2 15:53:53 192.168.2.145 BARIX BCL Interpreter, V1.5Dec 2 15:53:53 192.168.2.145 Hi, everything is OK.Dec 2 15:53:53 192.168.2.145 BCL endBCL keywords are case insensitive. Parameters should be separated by a comma (',', ASCIIcharacter 44). For functions, the parameters should be in parenthesis, for example:I=PING("192.168.2.18",50)even if the value is not used:PING("192.168.2.18",50)3.1.2 CommentsIt is possible to have useful comments inside the source BCL file. The ' (apostrophe, ASCIIcode 39) character is used for commenting. All text after the apostrophe sign is ignored tillthe end of the line (CRLF).'This is our first program!SYSLOG "Hi, everything is OK"'end of our first program!END'send message using syslog commandFunctionally this program is exactly the same as the first program so the syslog output isidentical:Dec 2 15:53:53 192.168.2.145 BARIX BCL Interpreter, V1.5Dec 2 15:53:53 192.168.2.145 Hi, everything is OK.Dec 2 15:53:53 192.168.2.145 BCL end3.1.3 Command delimitersMost BCL statements can be delimited with new line (CRLF, ASCII codes 13,10) or ':' (colon,ASCII code 58) characters. 2 Comments and DIM statements (see section 4.1 Interger Arrays onpage 12) must be terminated with CRLF.3.1.4 Multi-line commandsIt is possible to write multi-line commands by putting an '&' character (ampersand) at theend of the line to be continued. An example follows:SYSLOG "1":SYSLOG"2":SYSLOG &1 For more information about syslog, see section 14, page 762 Using space (' ', ASCII code 32) as separator, which was possible in previous versions, is considered deprecated and will notbe supported in future versions of BCL.Barix AG | 7/106
