STRPOS Function (Code, Text)

Searches for the first occurrence of substring inside a string.

Syntax

  
Position := STRPOS(String, SubString)  

Parameters

String
Type: Text constant or code

The string in which you want to search.

SubString
Type: Text constant or code

The substring for which you want to search.

The STRPOS function is case-sensitive.

Property Value/Return Value

Type: Integer

The position of SubString in String.

Remarks

The STRPOS function returns the position of the first occurrence of the substring.

If SubString cannot be found, then the function returns zero.

If String or SubString is empty, then the function returns zero.

Example 1

This example shows how to use the STRPOS function.

This example requires that you create the following text constants in the C/AL Globals window.

Text constant ENU value
Text000 'ABC abc abc xy'
Text001 'abc'
Text002 'The search for the substring: >%1<\'
Text003 'in the string: >%2<,\'
Text004 'returns the position: %3'
String := Text000;  
SubStr := Text001  
Pos := STRPOS(String, SubStr);  
MESSAGE(Text002 + Text003 + Text004, SubStr, String, Pos);  
// The STRPOS function is case-sensitive. Furthermore, it only  
// returns the position of the 1st occurrence of the substring.  

The message window displays the following:

The search for the substring: >abc<

in the string: >ABC abc abc xy<

returns the position: 5

Example 2

Pos1 := StrPos("abc",""); // Returns 0.  
Pos2 := StrPos("abc","c"); // Returns 3.  
Pos3 := StrPos("abc","bc"); // Returns 2.  
Pos4 := StrPos("abc","x"); // Returns 0.
