CRBasic Example 13. Foreign‐Language Support
‘Declare a constant to concatenate six non-English characters
Const PTempUnits = CHR(HexToDec ("C9"))+ CHR(HexToDec ("E3"))+ CHR(HexToDec("CA")) _
+ CHR(HexToDec ("CF")) + CHR(HexToDec("B6")) + CHR(HexToDec ("C8"))
‘Declare a constant to concatenate four non-English characters
Const PTempAlias = CHR(HexToDec ("CE"))+ CHR(HexToDec ("C2")) + CHR(HexToDec("B6")) _
+ CHR(HexToDec ("C8"))
‘Declare as Alias and Units non-English words concatenated above
Alias PTemp = PTempAlias
Units PTemp = PTempUnits
7.7.3.5 Declared Sequences
Declaration sequences include DataTable() / EndTable and Sub() / EndSub.
Certain sequences that may be incidental to a specific application also need to be
declared. These include ShutDown / ShutdownEnd, DialSequence() /
EndDialSequence, ModemHangup() / EndModemHangup, and
WebPageBegin() / WebPageEnd sequences. Declaration sequences can be
located:
1. prior to BeginProg
2. after EndSequence or an infinite Scan() / NextScan and before EndProg or
SlowSequence
3. immediately following SlowSequence. SlowSequence code starts executing
after any declaration sequence. Only declaration sequences can occur after
EndSequence and before SlowSequence or EndProg.
7.7.3.5.1 Data Tables
Data are stored in tables as directed by the CRBasic program. A data table is
created by a series of CRBasic instructions entered after variable declarations but
before the BeginProg instruction. These instructions include:
DataTable()
'Output Trigger Condition(s)
'Output Processing Instructions
EndTable
A data table is essentially a file that resides in CR800 memory. The file is written
to each time data are directed to that file. The trigger that initiates data storage is
tripped either by the CR800's clock, or by an event, such as a high temperature.
Up to 30 data tables can be created by the program. The data tables may store
individual measurements, individual calculated values, or summary data such as
averages, maxima, or minima to data tables.
Each data table is associated with overhead information that becomes part of the
ASCII file header (first few lines of the file) when data are downloaded to a PC.
Overhead information includes:
• table format
• datalogger type and operating system version,
