FUNCTION ByteReOrder (ByteStr$,ReOrder$ ) as string
A function that reorder bytes in string.
Detailes:
ReOrder$  -
Defines the  order of bytes following  in ByteStr$

abcde  initial string
2145
    output order - i.e. 
2 byte to 1 posicion
 
1 byte to 2 posicion
4 byte to 3 posicion
5 byte to 4 posicion

badee output  string

Examples:

number$ =ByteReOrder ("0123","2143" )

Return
 "1032"
------------------------
inpStr$="1234":             print "inpStr$=" ,inpStr$
reOrder$="222143":      print "reOrder$=" ,reOrder$
ssd$=ByteReOrder (inpStr$,reOrder$ )
print "ByteReOrder="+ ssd$

Return
  ByteReOrder=2221
-------------------------
number$ =ByteReOrder ("1234","143" )
Return  1434
-------------------------
ssd$=ByteReOrder ("abcde","2149" )

Error:  ShowMessage( "ReOrder index outbound input string"):exit FUNCTION

there are no 9 byte in "abcde" string
 


FUNCTION CNumByte (Num, Num_Type as short ) as string

FUNCTION CNumByte  converts   number of Num_Type type to bytes sequence.

Num_Type can be next value:
CONST Num_SHORT = 2
CONST Num_WORD = 3
CONST Num_LONG = 4
CONST Num_DWORD = 5
CONST Num_SINGLE = 6
CONST Num_DOUBLE = 8
 


FUNCTION CByteNum (ByteStr$,Num_Type as short ) as variant

FUNCTION CByteNum  converts bytes sequence to  number of Num_Type type 


Num_Type can be next value:

CONST Num_SHORT = 2
CONST Num_WORD = 3
CONST Num_LONG = 4
CONST Num_DWORD = 5
CONST Num_SINGLE = 6
CONST Num_DOUBLE = 8

Examples:
iNitNum=1234.56789

SngStr$=CNumByte (iNitNum, Num_siNGLE )

DblStr$=CNumByte (iNitNum, Num_DouBLE )

print "Num_siNGLE=",CByteNum (SngStr$,Num_siNGLE )
print "Num_DouBLE=",CByteNum (DblStr$,Num_DouBLE )

Return 
iNitNum=1234.567890000

SngStr$=,R?D
DblStr$=зЖф"EJ"@

Num_siNGLE=1234.567871094
Num_DouBLE=1234.567890000


 LIKE Function - pattern matching routine for Rapid-Q by William Yu
 This emulates the VB LIKE operator.
 Thanks to Thomas Binder for the original C code

 ? Any single character.
 * Zero or more characters.
 # Any single digit (0-9).
 [charlist] Any single character in charlist.
 [!charlist] Any single character not in charlist.

 A group of one or more characters (charlist) enclosed in brackets ([ ])  can be used to match any single character in string and can include almost  any character code, including digits.

 Note: To match the special characters left bracket ([), question  mark (?), number sign (#), and asterisk (*), enclose them in brackets.
 The right bracket (]) can't be used within a group to match itself, but  it can be used outside a group as an individual character.

 By using a hyphen (-) to separate the upper and lower bounds of the range,  charlist can specify a range of characters. For  example, [A-Z] results in  a match if the corresponding character position in string contains any  uppercase letters in the range A-Z. Multiple ranges are included within  the brackets without  delimiters.

'-- Test code

print "Like('24','##')=", Like("24","##")

?"Like(aBBBa, a*a)=", Like("aBBBa","a*a")
?Like("F","[!A-Z]")
?Like("a2a","a#a")
?Like("aM5b","a[A-GL-P]#[!c-e]")
?Like("BAT123khg","B?T*")
?Like("CAT123khg","B?T*")

?Like("Combine(10, 20) = 30", "*(*?,*?)*=*#")

return

Like('24','##')=1
Like(aBBBa, a*a)=1
