A reader queried how a template could be modified before display without modifying the file copy of the template. If @PSEUDO is loaded with the template record, and WINDOW is called with the literal NOREAD in the command line, the template will be read from @PSEUDO rather than file. The value of @PSEUDO could then be changed using FIELDSTORE before CATALYST was called, for example to change a title before display -
@PSEUDO = XLATE("TEMPLATES","TYPES","","X")
@PSEUDO = FIELDSTORE(@PSEUDO,CHAR(247),6,1,"Test")
CALL CATALYST("W","TYPES NOREAD")
Note - when using NOREAD a template name MUST still be given (this can be anything as it seems only to be used to keep position within @SENTENCE). Further the sixth "field" (delimited using CHAR(247)s, ie the title) MUST contain something otherwise the system will display an error message and return.
