\n

limits=X<\/p>\n<\/td>\n

\n

Optional. Specify the number of limits allowed. The default is 200.<\/p>\n<\/td>\n<\/tr>\n

\n

tables=X<\/p>\n<\/td>\n

\n

Optional. Specify the number of calibration tables allowed. The default is 100.<\/p>\n<\/td>\n<\/tr>\n

\n

alias=X<\/p>\n<\/td>\n

\n

Optional. Specify the number of aliases variables names. The default is 100.<\/p>\n<\/td>\n<\/tr>\n

\n

rarray=X<\/p>\n<\/td>\n

\n

Optional. Specify the number of real array variables. The default is 10.<\/p>\n<\/td>\n<\/tr>\n

\n

iarray=X<\/p>\n<\/td>\n

\n

Optional. Specify the number of integer array variables. The default is 10.<\/p>\n<\/td>\n<\/tr>\n

\n

sarray=X<\/p>\n<\/td>\n

\n

Optional. Specify the number of string array variables. The default is 10.<\/p>\n<\/td>\n<\/tr>\n

\n

larray=X<\/p>\n<\/td>\n

\n

Optional. Specify the number of logical array variables. The default is 10.<\/p>\n<\/td>\n<\/tr>\n

\n

PAM_stats=X<\/p>\n<\/td>\n

\n

Optional. Specify the maximum number of pam_specs variables that can be specified as “AVER”. The default is 1000.<\/p>\n<\/td>\n<\/tr>\n

\n

log_vars=X<\/p>\n<\/td>\n

\n

Optional. Specify the maximum number of variables that can be logged with either floger or dlogger. The default is 1000.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/dd>\n<\/dl>\n

Example:<\/h3>\n
\n
\n

sys_start<\/strong> filename real=1000 integer=384 logical=1000 string=256 stat=128 expr=1000 saved_data=256 limits=200 tables=256 long_tables=12 PAM_stats=100 log_vars=1200<\/p>\n

The above example performs initialization and overrides the default values with the specified values for each of the specified data types. By specifying 1200 for the log_vars argument, upto 1200 variables can be logged within the dlogger and floger programs.<\/p>\n

sys_start<\/strong><\/p>\n

The above command performs initialization and accesses the file logi_specs.nnn for some of the initialization information.<\/p>\n<\/dd>\n<\/dl>\n

Notes:<\/h3>\n
\n
\n

Use the ‘show_mem’ command to check shared memory usage. Array sizes for general use variables are flexible and configurable.<\/p>\n<\/dd>\n<\/dl>\n
