By default, a Natural system error message consists of: the name of the program and the number of the line that caused the error, followed by the actual text of the message. Depending on the size of the window in which the message is displayed, the actual text may be truncated. With the terminal command %MSGSF, you can avoid such truncation.

Command	Function
%MSGSF=ON	System error messages will be displayed in full; that is, program name, line number and actual message text will be displayed (this is the default).
%MSGSF=+
%MSGSF=T
%MSGSF=OFF	System error messages will be displayed in short form; that is, only the actual message text will be displayed (but not the program name and line number).
%MSGSF=-
%MSGSF=F

Notes:

1. Instead of ON, you can also specify "+" or "T" (true). Instead of OFF, you can also specify "-" or "F" (false).
2. The display format of system error messages can also be controlled with the profile parameter MSGSF (see the Parameter Reference).
