Comments

Comments can be any text enclosed in double quotes and may be written anywhere within a command except within names, keywords, operators, numbers or character constants (for syntactical reasons). A comment may also be written in an otherwise empty command line:

/   "Preparations for calling procedure P.YY"
/COPY-FILE OLD-FILE "created by program A.23" , -
/          NEW-FILE "required in procedure P.YY"

The two-character string &* causes any line contents that follow it to be ignored (end-of-line comment). It can thus be used to (temporarily) comment out a command line without requiring specific handling of any quotes contained in that line:

/     START-EXE YZ-ERZEUGEN
/ &*  CALL-PROC P.CONVERT,(YZ-FILE) "Convert umlauts"
/     START-PERCON
//    ASSIGN-INPUT-FILE DISK-FILE(...)
