Logical Names
This section describes the logicals SWAP requires to run.  These logicals, if defined, must be in the system table.

SWAP_CDU - This logical points to the [SWAP.CDU] directory.  It is used to access the SWAP command definition table.  SWAP_CDU is optional.

SWAP_COM - This logical points to the [SWAP.COM] directory.  It is used to access SWAP DCL command procedures.  SWAP_COM is optional.

SWAP_DAT - This logical points to the [SWAP.DAT] directory.  This logical is maintained for compatibility with other products by Saiga Systems.  SWAP_DAT is optional.

SWAP_DOC - This logical points to the [SWAP.DOC] directory.  The help files are stored in this directory.  SWAP_DOC is optional.

SWAP_EXE - This logical points to the [SWAP.EXE] directory.  It is used to access the SWAP executables.  It is required.  If you cannot access SWAP check to see that this logical is defined in the system table.

SWAP$VAR_DELIM - If this logical is defined to a single character that character will be treated as the delimiter for variables instead of the default character, “%.” For example, to make the vertical bar character your variable delimiter:

$ define swap$var_delim “|” [/system]

if /system is added the variable delimiter will be set for everybody using swap on this node. Omitting /system will set the delimiter for your current process only.
