“The battery is 12.4 Volts”
12.4 Volts
12.4 Volts
The battery = 12.4 Volts
The battery is 12.4 Volts
The battery is 12.4 Volts
The battery is 12.4 Volts
THE BATTERY IS 12.4 VOLTS
The b
Volts
CRBasic Example 49. Formatting Strings
Objective:
Format the string "The battery is 12.4 Volts"
Use CRBasic expression:
StringVar(11) =
Mid ("The battery is 12.4 Volts", _
InStr (1,"The battery is 12.4 Volts"," is ",2)+3, Len ("The battery is 12.4 Volts"))
Result:
12.4 Volts
7.8.13.8 Formatting String Hexadecimal Variables
Table 44. Formatting Hexadecimal Variables - Examples
Expression Comment Result
CRLFNumeric(1) = &H0d0a Add leading zero to hex step 1 3338
StringVar(20) = "0" & Hex(CRLFNumeric) Add leading zero to hex step 2 0D0A
CRLFNumeric(2) = HexToDec(Strings(20)) Convert Hex string to Float 3338.00
7.8.14 Data Tables
CRBasic Example 50. Two Data Intervals in One Data Table
'CRBasic program to write to a single table with two different time intervals.
'Note: this is a conditional table, check the table fill times in the Status table.
'For programs with conditional tables AND other time driven tables, it is generally
'wise to NOT auto allocate the conditional table; set a specific number of records.
'Declare Public Variables
Public PTemp, batt_volt, airtempC, deltaT
Public int_fast As Boolean
Public int_slow As Boolean
Public counter(4) As Long
