Stack Management Commands

STK.GetType

Previous Next

MiniRobotLanguage (MRL)

 

STK.GetType|$$STK[|$$TYP]

Get the data type of the stack.

 

Intention

The STK.GetType command retrieves the type of data stored in the stack. This helps ensure that operations performed on the stack are consistent with the data type.

The command returns the following values:

1 - String

2 - Integer

3 - Extended (Float)

0 - Error

If the optional parameter $$TYP is provided, the result will be stored there.

 

 

Syntax

 

STK.GetType|$$STK[|$$TYP]

 

Parameter Explanation

 

P1 - $$STK: The stack handle whose data type is to be retrieved.

P2 - $$TYP (Optional): A variable to store the result of the operation. If omitted, the result is returned to the top of the stack.

 

Example

 

'***********************************

' Example 1: Get Type of a Stack

'***********************************

STK.New|$$STK|s

STK.GetType|$$STK|$$TYP

JIV.$$TYP!1|Lab_Failed

STK.End|$$STK

ENR.

 

'***********************************

' Example 2: Get Type Without Variable

'***********************************

STK.New|$$STK|i

STK.GetType|$$STK

STK.Peek|$$STK|$$RES

JIV.$$RES!2|Lab_Failed

STK.End|$$STK

ENR.

 

 

 

Remarks

- The command ensures type safety by verifying the data type of the stack.

- If the stack handle is invalid, the command returns 0 (Error).

 

Limitations:

- The stack handle must be valid before calling STK.GetType. Invalid handles will return an error.
