COUNT TRAILING WHITE SPACE IN UNDELIMITED STRINGS

Syntax:

[DO NOT] COUNT TRAILING [WHITE] SPACE[S] IN [UNDELIMITED] STRINGS

Function:

This command determines the way in which fpt interprets a string which continues from one line to the next, so that no string delimiter is written at the end of the first line. Compilers differ in their treatment of this situation. Some always pad undelimited strings with spaces up to the end of the code line (normally column 72). Some compilers count the number of space or tab characters actually written in the input file, and use this number to determine the string length. Some simply issue an error message.

In Fortran 90 free format, fpt uses Fortran 90 continuation characters to link strings split between lines. When writing in fixed format, wherever possible, fpt writes the strings in the output files with delimiters before the line ends. Strings in executable code are linked across lines by string catenation // operators. Strings in format specifications are linked by commas.
