  Here's a sample class for basic text-field manipulation rules. Below, I will provide the code that calls the methods from this class

  extern alias aControllerInterlop; //be sure to use aliases! this line needs to be first
  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using aControllerInterlop::ABBYY.FlexiCapture; 
  namespace FCToolkit
  {
      public class TextRule
      {
          protected IRuleContext _fieldRuleContext;
  
          // object constructor
          public TextRule(IRuleContext context)
          {
              _fieldRuleContext = context;
          }        
  
          // Static method: Pads the field's text with leading zeroes
          public static void PadWithLeadingZeroes(IRuleContext ruleContext, int FinalCharacterCount)
          {
              string modifiedText = ruleContext.Fields[0].Text;
              int initialCharacterCount = modifiedText.Length;
              for (int cidx = initialCharacterCount; cidx < FinalCharacterCount; cidx++)
              {
                  modifiedText = "0" + modifiedText;
              }
              ruleContext.Fields[0].Text = modifiedText;
          }      
  
          // static method: passes values from a text block to other text fields
          public static void GetRegistrationFieldsFromBarcode(IRuleContext ruleContext)
          {
              // Field("Barcode") R
              // Field("DocumentId") RW
              // Field("SourceId") RW
              if (ruleContext.HasField("Barcode") && ruleContext.HasField("DocumentId") && ruleContext.HasField("SourceId"))
              {
                  string barcodeValue = ruleContext.Field("Barcode").Text;
                  ruleContext.Field("DocumentId").Text = barcodeValue.Substring(0, 9);
                  ruleContext.Field("SourceId").Text = barcodeValue.Substring(9, 1);
              }
              else if (ruleContext.HasField("DocumentId") && ruleContext.HasField("SourceId"))
              {
                  string barcodeValue = ruleContext.Field("DocumentId").Text;
                  ruleContext.Field("SourceId").Text = barcodeValue.Substring(9, 1);
              }
              else
              {
                  ruleContext.ErrorMessage = "A field or field alias is incorrectly named";
              }
          }
  
          public static void GetBatchIdFromCoverSheet(IRuleContext Context)
          {
              // Field("CoversheetImageSource") is a service field set to image source
              // Field("CoversheetImageSource") R
              // Field("BatchId") RW
              if (Context.Field("BCSImageSource").Text != "")
              {
                  string bcsImageSource = Context.Field("CoverSheetImageSource").Text;
                  Context.Field("BatchId").Text = bcsImageSource.Substring(bcsImageSource.Length - 31, 31 - 6);
              }
          }
      }
  }

  For some reason, this code doesn't want to allow my html summaries for the methods in the comment window. I'll add a post detailing intellensense summaries in my third post on this topic.

  Also, if anybody knows how to prevent the text wrap here, please feel free to let me know

  To call one of these static methods in FlexiCapture, you first need to build the project and add it to a document definition's .Net References as an 'attached file'.

  Create a new rule within a text field and navigate to the script editor. Use the following script to invoke the class method:

  // this sample code requires the field script window to be set to c# .net
  FCToolkit.PadWithLeadingZeroes(Context, 3);
  
  // This method pads a text field with leading zeroes until it is 3 characters long
  // EX: 5 -> 005
  // EX: 23 -> 023
  // EX: 653 -> 653
