deck.name *SPEC file.no blocksize activity open close
The 'deck.name' and 'file.no' are used to identify the file as the same file described on a *FILE card. Unless the same 'deck.name' and 'file.no' appear on a *FILE in the deck the *SPEC Card will be ignored.
'blocksize' is normally a number (0-999) but may be left blank. A number in this field specifies the maximum number of words to be input or output in a single block. It may be desirable to change the blocksize in an attempt to obtain better input/output processing speeds or tape utilization. Conflict with file specifications entered in the Commercial Translator Environment section must be avoided. The loader will check most normal situations in accordance with information supplied to it by the Compiler.
'activity' may be specified as a number 0-99 or may be left blank. A number in this field specifies the relative activity of the file in respect to other files and is used by the Loader in the allocation of buffer areas.
The 'open' options are:
- N — No rewind
- R or blank — Rewind
The 'close' options are:
- U — Rewind and unload
- R or blank — Rewind
- N — No Rewind
- S — No file mark or trailers, no rewind
Appendix 90.08 contains a chart showing the source of the fields of the *SPEC card when it is generated by the Compiler.
E. *POOL Card
The *POOL card designates which files are to share common buffer areas. The format of this card is:
1-6 7-11 14-15 17-20 23-25 27
deck.name *POOL pool.no blocksize buffer.cnt file1, file2...filen
The 'blocksize and buffer count' specifications are described in the Environment Description POOL card (section 02.06).
- If the file referenced is described in the deck named on the *POOL card, specification of the file number shown in the compiler file list adequately
