# Help converting letters to number

## Recommended Posts

I was woundering how i would set this up: I a a varibale that has letters and numbers, the lenght of the variable can change. I was wanting to convert the letters to a number so it is all numbers. I'm pretty sure ill have to make it a string but then im kinda lost.

```\$var='A7601000aFBFBEFB33528985'
LettersToNumbers()
;===============================================================================
Func LettersToNumbers()
If \$var = 'A' Then \$var = 1
If \$var = 'B' Then \$var = 2
If \$var = 'C' Then \$var = 3
If \$var = 'D' Then \$var = 4
If \$var = 'E' Then \$var = 5
If \$var = 'F' Then \$var = 6
If \$var = 'G' Then \$var = 7
If \$var = 'H' Then \$var = 8
If \$var = 'I' Then \$var = 9
If \$var = 'J' Then \$var = 10
If \$var = 'K' Then \$var = 11
If \$var = 'L' Then \$var = 12
If \$var = 'M' Then \$var = 13
If \$var = 'N' Then \$var = 14
If \$var = 'O' Then \$var = 15
If \$var = 'P' Then \$var = 16
If \$var = 'Q' Then \$var = 17
If \$var = 'R' Then \$var = 18
If \$var = 'S' Then \$var = 19
If \$var = 'T' Then \$var = 20
If \$var = 'U' Then \$var = 21
If \$var = 'V' Then \$var = 22
If \$var = 'W' Then \$var = 23
If \$var = 'X' Then \$var = 24
If \$var = 'Y' Then \$var = 25
If \$var = 'Z' Then \$var = 26
MsgBox  (0,'',\$var)
EndFunc
;===============================================================================```

russell,

What you want to do is extremely easy. StringMid will look at each of the charcters in turn - use StringLen to get the count. Then Asc (look in the Helpfile for details) will be of great help - all you need to do is check that the returned value is within the A-Z range and then subtract 64. To get it all into a string just create an empty string before you loop through the characters and append each one (either raw on converted) using &= as you deal with it.

But could I ask why you want to do this? The process is essentially irreversible as there is no way to determine which of the numbers in the final are actually numbers and which are converted letters.

Here the code which M23 described above more or less.

```\$var='A7601000aFBFBEFB33528985'

MsgBox(0, "Test", LettersToNumbers(\$var))

Func LettersToNumbers(\$sString)
If Not StringLen(\$sString) Then Return SetError(1, 0, 0)
Local \$aChars = StringSplit(\$sString, "", 2), \$i, \$sNumber, \$s
For \$i = 0 To UBound(\$aChars) - 1
\$s = Asc(StringUpper(\$aChars[\$i])) - 64
Switch \$s
Case 1 To 26
\$sNumber &= \$s
Case Else
\$sNumber &= \$aChars[\$i]
EndSwitch
Next
Return \$sNumber
EndFunc```

UEZ thankyou, i shall study and try to master this. Melba23 thankyou for the guidance where to start my skills. Im using this to make a unique computer id, that string of numbers is bits of data from CPU,hdd etc. Thankyou both so much

russell,

Rather than reinvent the wheel, you might like to look at this UDF from guinness.

Here is another implementation

```#include <BackRef.au3>

\$var = 'A7601000aFBFBEFB33528985'
MsgBox(64, "Return:", GlobalBackRef(\$var, '(.*?)([A-Za-z])(.*)', 'RetNum'))

Func RetNum(\$s_Match)
Return Asc(StringUpper(\$s_Match)) - 64
EndFunc   ;==>RetNum```

PredictText: Predict Text of an Edit Control Like Scite. Remote Gmail: Execute your Scripts through Gmail. StringRegExp:Share and learn RegExp.

Run As System: A command line wrapper around PSEXEC.exe to execute your apps scripts as System (LSA). Database: An easier approach for _SQ_LITE beginners.

MathsEx: A UDF for Fractions and LCM, GCF/HCF. FloatingText: An UDF for make your text floating. Clipboard Extendor: A clipboard monitoring tool.

Custom ScrollBar: Scroll Bar made with GDI+, user can use bitmaps instead. Restrict text in an Edit Control through a Regular Expression.
