# TRROR(2)

Print LAM system error message.

## NAME

TRROR - Print LAM system error message.

## SYNOPSIS

subroutine TRROR (strname)\
 character strname\*(\*)

## DESCRIPTION

The most recent error message is displayed. Many LAM subroutines have an *ierror* argument that returns an error code. If *TRROR()* is invoked immediately after detecting an error condition from a LAM subroutine, the description corresponding to the *ierror* code will be displayed. The error message will be preceded by the contents of *strname*.

## EXAMPLE

```
call KENTR('app', 0, ierror)
if (ierror .ne. 0) call TRROR('knit')
```
