!define LOGICLIB_STRCMP
!include LogicLib.nsh
</highlight-nsis>

== How To Use ==

=== Syntax ===

<highlight-nsis>
${CharToASCII} $ResultVar "Character"
</highlight-nsis>
or
<highlight-nsis>
Push "Character"
Call CharToASCII
Pop $ResultVar
</highlight-nsis>

=== Parameters ===

; ResultVar
: Variable where the ASCII code is returned. The function returns 0 if no ASCII code was found.

; Character
: The Character for ASCII conversation

=== Example ===

${CharToASCII} $0 "T"
;$0 = 84
</highlight-nsis>

== Function Code ==

<highlight-nsis>
!define CharToASCII "!insertmacro CharToASCII"

!macro CharToASCII AsciiCode Character
Push "${Character}"
Call CharToASCII
Pop "${AsciiCode}"
!macroend

Function CharToASCII
Exch $0 ; given character
Push $1 ; current character
Push $2 ; current Ascii Code

StrCpy $2 1 ; right from start
Loop:
IntFmt $1 %c $2 ; Get character from current ASCII code
${If} $1 S== $0 ; case sensitive string comparison
StrCpy $0 $2
Goto Done
${EndIf}
IntOp $2 $2 + 1
StrCmp $2 255 0 Loop ; ascii from 1 to 255
StrCpy $0 0 ; ASCII code was'nt found -> return 0
Done:
Pop $2
