(defaults to not-significant if omitted) file

∗The following values are possible for file type:

U = Enscribe unstructured R = Enscribe relative

E = Enscribe entry-sequenced

∗∗This is the standard Guardian file attribute that stands for the maximum record length.

∗∗∗The maximum-string-length parameter must be specified.

∗∗∗∗Line numbers are not preserved. If the value specified for the max-extents attribute is exceeded, max-extents is automatically increased (in increments, up to the system limit) and the lines renumbered.

The maximum number of lines allowed for file type 101 is 10,000,000. For more information, see the Guardian Procedure Calls Reference Manual.

Note. If a DEFINE by the name of _ZOSF_FIXED_AS_UNSTRUCT exists when the FTAM processes are started, and the string-significance parameter is set to FIXED in the request, the file created or selected will be an unstructured file with maximum-string-length of 4096 bytes.

Note. Though a default value for each parameter is proposed, if there are any user-defined default values available for particular combinations on a file type and file code, then that will override the system-defined default parameter values.

Select-Open Mappings

Table 4-7 shows the FTAM document types that correspond to each Compaq file type that can be selected, opened, and read. This table indicates the default parameter values for the document types that Compaq supports, whereas Table 4-5, earlier in this section, indicates the full range of parameter values for these document types.
