(PowerBuilder) Append Big-Endian or Little-Endian Integers

Demonstrates how to append integers in big-endian or little-endian byte order to a BinData.

Note: This example requires Chilkat v9.5.0.77 or greater.

// Use "Chilkat_9_5_0.BinData" for versions of Chilkat < 10.0.0

// The hex value of decimal 123456789 is 0x075BCD15
x = 123456789

// Appending little-endian causes bytes to be
// appended in the order 0x15, 0xCD, 0x5B, 0x07
li_LittleEndian = 1
li_Success = loo_Bd.AppendInt4(x,li_LittleEndian)

Write-Debug loo_Bd.GetEncoded("hex")
// Output is: 15CD5B07

// Now append the same integer in big-endian byte order.
// Appending bit-endian causes bytes to be
// appended in the order 0x07, 0x5B, 0xCD, 0x15
li_LittleEndian = 0
loo_Bd.AppendInt4(x,li_LittleEndian)

Write-Debug loo_Bd.GetEncoded("hex")
// bd now contains: 15CD5B07075BCD15

// -------------------------------------------
// Now do the same thing with 16-bit integers
loo_Bd.Clear()

// 1234 decimal = 0x04D2 hex.
x = 1234

li_LittleEndian = 1
loo_Bd.AppendInt2(x,li_LittleEndian)

Write-Debug loo_Bd.GetEncoded("hex")
// Output is: D204

li_LittleEndian = 0
loo_Bd.AppendInt2(x,li_LittleEndian)

Write-Debug loo_Bd.GetEncoded("hex")
// Output is now: D20404D2
