Convert a PostScript file to a file which can be mailed without requiring encoding or other special handling.
This utility cannot produce correct output for some PostScript files.
PMDF PSWRAP input-file-spec [output-file-spec]
Qualifiers Defaults /RECORD_LENGTH=width /RECORD_LENGTH=76
input-file-specThe name of the PostScript file to process. Only a single file can be specified; wildcards cannot be used.
output-file-specAn optional parameter specifying the name of the new PostScript file to output. If no file name is specified, then the output file will have the same name as the input file.
The PSWRAP utility can be used to convert a PostScript file to a file with varying length records, carriage return carriage control, and no record longer than the specified length.
This utility cannot produce correct output for some PostScript files. PostScript files contain complex programs written in the PostScript language. The PSWRAP utility understands the PostScript language syntax and can perform syntactically correct line wrappings. However, some PostScript files contain data which cannot be wrapped, for instance, input to the PostScript "readstring" operator. Short of actually interpreting the PostScript file, it is not possible to determine whether or not it is safe to wrap lines in the file.1 The PSWRAP utility ignores this issue and as such could output non-functioning PostScript. Be sure to test (e.g., print) the output of PSWRAP before mailing it to someone else or deleting the input file. QuarkXPress, for example, produces output which PSWRAP will not properly wrap. If a readstring operator is seen in the PostScript file, a PMDF-W-READSTRSEEN warning message will be output.
/RECORD_LENGTH=lengthMaximum record length to allow in the output file. If not specified, a length of 76 bytes will be imposed.
In the following example the file JACS_PAPER2.PS is processed and the new file JACS.PS output. The resulting file is then printed to assure validity and then mailed to another user.
$ PMDF PSWRAP JACS_PAPER2.PS JACS.PS $ PRINT/QUEUE=PS_PRINTER/NOTIFY JACS.PS Job JACS (queue PS_PRINTER, entry 741) started on PS_PRINTER $ Job JACS (queue PS_PRINTER, entry 741) completed $ MAIL/SUBJECT="Latest draft" JACS.PS "IN%""BOB@EXAMPLE.COM"""
1 After a determination has been made, the underlying PostScript program represented by the file must be rewritten.
