If the environment variable RXSAVETOKENS is set to YES, Object Rexx stores the internal format at the end of the program script. When this program is executed the next time, the so-called parsing process can be skipped and the program can be started faster.
Whenever you modify your program script, the image at the end of the file is discarded by the editor and the modifications are therefore recognized by the Object Rexx interpreter. Using this mechanism requires an editor that can handle files terminated by Ctrl+Z (EOF).
If the editor you are using does not discard the data after EOF, changes within the ASCII code are not reflected in the tokenized script.
