String manipulation

[jsampsonyyyyy]

I am wondering if it is possible to delete the beginning of a string if it consists of a certain substring. E.g. if, and only if, the string begins with "Joe " then delete "Joe " leaving the rest of the string intact. I have found "replace" but that would remove "Joe " wherever it was in the string, not necessarily at the beginning.

An integer variable may be set to the position of a substring within the text.  So if you find it at position 1, then "replace".  There's an option within "replace" to do it once only, or for all occurrences.

This script illustrates one way to check for "Joe " at the start of the string:

 

Quote

Variable Set String %x% to "Joe Blow"
Variable Set String %x%: Prompt
Variable Modify String: Copy part of text in %x% starting at 1 and 4 characters long to %Name%
If Variable %Name% Equals "Joe "
  Variable Modify String: Delete part of text from %x% starting at 1 and 4 characters long
End If
Text Box Display: Result

Quote

<VARIABLE SET STRING Option="\x00" Destination="%x%" Value="Joe Blow" NoEmbeddedVars="FALSE"/>
<VARIABLE SET STRING Option="\x01" Destination="%x%" Prompt="What is the name?" Mask="FALSE" OnTop="TRUE" Left="Center" Top="Center" Monitor="0"/>
<VARIABLE MODIFY STRING Option="\x09" Destination="%Name%" Variable="%x%" Start="1" Count="4" NoEmbeddedVars="FALSE"/>
<IF VARIABLE Variable="%Name%" Condition="\x00" Value="Joe " IgnoreCase="FALSE"/>
<VARIABLE MODIFY STRING Option="\x0A" Destination="%x%" Start="1" Count="4"/>
<END IF/>
<TEXT BOX DISPLAY Title="Result" Content="{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033{\\fonttbl{\\f0\\fnil\\fcharset0 Tahoma;}{\\f1\\fnil Tahoma;}}\r\n\\viewkind4\\uc1\\pard\\lang4105\\f0\\fs20 The result is \"%x%\"\\lang1033\\f1\\fs14 \r\n\\par }\r\n" Left="Center" Top="Center" Width="278" Height="200" Monitor="0" OnTop="TRUE" Keep_Focus="TRUE" Mode="\x00" Delay="0"/>
