**Setup( **//constraints //[//, startline//]// //**)**

{{blk2blue.jpg|blk2blue.jpg}}

| **Setup** | Sets the search constraints. |
| //constraints// | The label of a structure containing the search constraints. The structure must have the same structure as the FindGroup GROUP declared in ABASCII.INC. |
| //startline// | The offset or position of the line at which to begin the search, typically the current line position. If omitted, //startline //defaults to one (1). |

The **Setup **method sets the search constraints. The AsciiSearchClass object applies the constraints when searching the text file.

**Implementation:**

The ABC Library does not call the Setup method. The Setup method is provided so you can do custom searches outside the normal AsciiViewerClass process (without using the Ask method).

The Next method applies the search constraints set by the Setup method. The constraints include the text to search for, the direction in which to search, and whether or not the search is case sensitive.

The FindGroup GROUP is declared in ABASCII.INC as follows:

**FindGroup  GROUP,TYPE**

**What     PSTRING(64)   !text to look for**

**MatchCase   BYTE       !case sensitive?**

**Direction   STRING(4)  !either 'Up  ' or 'Down'**

**      END**

**Example:**

**MyAsciiSearchClass.Ask PROCEDURE**

**Constraints  LIKE(FindGroup)**

** CODE**

** Constraints.MatchCase = False       !never case sensitive**

** Constraints.Direction = 'Down'      !always search downward**

** !prompt end user for search value**

** SELF.Setup(Constraints,StartLine)   !set search constraints**

** SELF.LineCounter=SELF.Next()        !execute search**

** IF SELF.LineCounter**

**!set to next line containing search value:**

**  SELF.FileMgr.SetLine(SELF.LineCounter)**

** ELSE**

**  MESSAGE(''''&CLIP(SELF.Constraints.What)&''' not found.')**

** END**
