Programming Commands XENIX Programming dosld - XENIX to MS-DOS cross linker. Syntax dosld [options] file ••• Description dosld links the object file{s) given by file to create a program for execution under MS­ DOS. Although sim ilar to ld, dosld has many options that differ significantly from ld. The options are described below. -D -H -L -M -c -F num -S num B-62 DS Allocate. This option instructs dosld to perform DS allocation. It is generally used in conjunction with the -H option. Load high. This option instructs dosld to set a field in the header of the executable file to tell MS-DOS to load the program at the highest available position in memory. It is most often used with programs in which data precedes code in the memory image. Include line numbers. This option instructs dosld to include line numbers in the listing file {if any). Note that dosld cannot put line numbers in the listing file if the source translator hasn't put them in the object file. Include public sy mbols. This option instructs dosld to include public sym bols in the list file. The sym bols are sorted twice, lexicographically and by address. Ignore case. This option instructs dosld to treat upper and lower case characters in symbol names as identical. Set stack size. This option should be followed by a hexadecimal number. dosld will use this number for the size in bytes of the stack segment in the output file. Set segment limit. This option should be followed by a decimal number between 1 and 1024. The number sets the limit on the nu mber of different segments that may be linked together. The default is 128. Note that the higher the value given, the slower the link will be.

<strong>XENIX</strong> Programming Programming Commands<br />

delta (continued)<br />

z-file Created during the execution of delta; removed during the execution of<br />

delta.<br />

d-file Created during the execution of delta; removed after completion of delta.<br />

/usr/bin/bdiff<br />

Program to compute differences between the "retrieved" file and the g-file.<br />

Warning<br />

Lines beginning with an SOH ASCII character (binary 001) cannot be placed in the SCCS<br />

file unless the SOH is escaped. This character has special meaning to sees (see sccsfile<br />

in "File Formats" in the <strong>XENIX</strong> <strong>2<strong>86</strong></strong> C Library <strong>Guide</strong>) and will cause an error.<br />

A get of many SCCS files followed by a delta of those files should be avoided when the<br />

get generates a large amount of data. Instead, multiple get/delta sequences should be<br />

used.<br />

If the standard input (-) is specified on the delta command line, the -m (if necessary),<br />

and -y options must also be present. Omission of these options causes an error to occur.<br />
