2: Variables and Computations

Command Purpose
alias_labels Process a specification file to define alias-label mappings in CyFlex.
arr_size Determine the size of array variable or a particular dimension of the variable.
arr_specs Process array specifications to configure array variables.
compvar

Evaluate user-defined expressions for computed variables, processing them based on specified intervals and events.

cvar

Create and initialize variables from the command line or from within a script. The arguments vary depending on the data type REAL variable.

em_ave Compute and print the mean, standard deviation, minimum, and maximum values for specified input variables over a given sampling interval.
garr Display array variables from shared memory with options to format output for quiet mode, units, and delimiters.
garr_all Display all active array variables in the CyFlex system including their values or filter them based on a provided string pattern.
gen_labels Process and configure general usage variables based on specification files.
gen_solver Find the roots for a general function f(X).
MEDOR_set Update a composition variable based on the concentrations defined in a set of real variables and to write an output file for loading into a database.
override_mon

Monitor the “overrideOFF” event that is a transition event associated with the “var_override” variable.

override_status Check the override status of a specified variable in CyFlex.
release_compvar Set an event to release a specified compvar instance, allowing it to clean up resources and exit.
release_evaluate Set an event to release the specified evaluate instance in CyFlex.
restore_array_var

Restore the contents of a specified CyFlex array variable from a disk file.

rstr_save_dat Restore variables from disk.
rvar Remove variable(s) created by the cvar application.
sarr Set array variable elements to a specified value based on provided label and dimensions.
sarru Set units for an array variable if a units string is provided or display the current units and units code.
save_list Specify a variable to maintain on disk.
save_status Save CyFlex variables on disk.
set_active Set the active flag for a specified CyFlex input variable in the transfer layer.
set_alias Create or modify an alias label to point to a specified target variable in CyFlex.
set_inactive Set the active flag to FALSE for a specified label in the CyFlex transfer layer.
show_gen Show computed strings.
sovr Set the override mode for a specified variable and optionally set its value if the master override is enabled.
spcl_chans Configure special channels based on a specification file for engine performance parameters.
svar

Set the value of specified variables in the system, supporting REAL, REAL_ARRAY, INTEGER, INTEGER_ARRAY, LOGICAL, LOGICAL_ARRAY, STRING, and STRING_ARRAY types, with checks for dimensional consistency and restrictions on certain variables.

varx_specs Process specifications that will be used by the var_transfer program.
var_transfer Transfer one CyFlex variable into another while applying an offset, gain, and recursive filter.
write_array_var

Use this utility to write the contents of a specified array variable to a disk file in /data/<label>.array.
