Form Command [FORM]
Displays information about a self-describing file created by programs such as Suprtool. These programs store information about the record layout such as field names, data types, length.
FORM [ $lp | $lpa | $lpb ] [ filename ]
(Default: filename = current Text file)
If filename is omitted and a workfile is currently active, Qedit uses the name of the Text file (see Verify Keep). An external filename can be specified.
If the file is not self-describing, Qedit displays the following message:
Error: File is not self-describing.
Self-describing files on MPE have a special filecode, SD. The data description information is stored in the file userlabels. For example, a self-describing file would look like this:
ACCOUNT= GL GROUP= DATA FILENAME CODE ------------LOGICAL RECORD----------- ----SPACE---- SIZE TYP EOF LIMIT R/B SECTORS #X MX X1DSBEDR SD 302B FA 3500 3500 13 320 1 1
The Form output looks like this:
Self-describing information for X1DSBEDR.DATA.GL File: X1DSBEDR.DATA.GL (SD Version B.00.00) Entry: Offset CHAR-FIELD X5 1 <<Sort# 1 >> INT-FIELD I1 6 DBL-FIELD I2 8 PACKED-FIELD P12 12 PACKED*-FIELD P12 18 QUAD-FIELD I4 24 ID-FIELD I1 32 LOGICAL-FIELD K1 34 DBLLOG-FIELD K2 36 ZONED-FIELD Z5 40 Limit: 3500 EOF: 3500 Entry Length: 44 Blocking: 64
LP listing
Overrides default output to $stdlist. $lp, $lpa and $lpb send output to a file with the same name as the option.
