To understand the compile-time error message format, consider this incorrect source line:
If this were line 7 of a source file ADD2.m, the compiler reports the compile-time error with the message:
S=B+C ^----- At column 4, line 7, source module ADD2 Variable expected in this context
The compile-time error message format consists of three lines. The first two lines tell you the line and location where the error occurred. The last line describes the M syntax error. The positioning accuracy of the carat pointing to the location of an issue in a source line depends on your terminal settings, particularly in UTF-8 mode where character widths are not uniform. If the line exceeds the terminal width as understood by GT.M, it replaces the carat line with an ARROWNTDSP error.
If you requested a listing file, it contains the same information and looks as follows:
. . 6 . . . 7 S=B+C ^----- Variable expected in this context 8 . . . . .
