4. RCDMRK
The RCDMRK type code causes insertion of a single character record mark constant in the indicated position. No description field specification is required since the compiler automatically provides a pictorial with a single A. Information may be freely moved into or out of this position subject only to the restriction imposed by its single character alphameric format.
5. LABEL
The type code LABEL allows the programmer to redefine with the indicated data description entries, the single 14 word label area in the Input/Output Control System from which all labels for output files are written and into which all input labels are read. This area may only be processed by the Commercial Translator programmer by using the FOR LABEL option on the Environment FILE cards. Use of the FOR LABEL option with a file causes IOCS to transfer control to the procedure.name specified with the option when the file is opened or closed, or when a reel switch occurs. Discussion of the implementation of this procedure may be found in Appendix 90.07. The type code LABEL and the FOR LABEL option provide the programmer with an IOCS oriented method of checking and forming non-standard labels. The restrictions limiting the length of labels processed in this manner to 14 words and dictating that portions of the FOR LABEL coding must be done in CRYPT may make an alternate method desireable; i.e., defining labels as records and processing with the GET and FILE verbs.
6. PARAM and FUNCT
These two type codes described in the General Information Manual are no longer in the language.
