 * 
 * Program V0520F4P creates 128 0/1 payment model HHS HCC variables,
 * 10 RXC variables, and a set of score variables for each enrollee 
 * in the PERSON SAS dataset (provided by the user).
 *
 * If an enrollee has at least one diagnosis in the DIAG SAS dataset
 * (provided by the user) then HHS HCC variables are created otherwise
 * HHS HCCs are set to 0 for the enrollee.  If an enrollee has at least 
 * one NDC in the NDC SAS dataset (provided by the user), or at least one 
 * valid code in the HCPCS file (provided by the user) then RXC variables 
 * are created otherwise RXCs are set to 0 for the enrollee. If HHS 
 * HCC variables and RXC variables are both set to 0 the score variables are based
 * on demographic variables (e.g., age, sex) and/or defaults.
 *
 * Score variables are created using calibration coefficients from three
 * models (Adult, Child, Infant), each with five `metal` levels
 * (Platinum, Gold, Silver, Bronze, Catastrophic):
 *
 *    1) Adult  Platinum        (AP)
 *    2) Adult  Gold            (AG)
 *    3) Adult  Silver          (AS)
 *    4) Adult  Bronze          (AB)
 *    5) Adult  Catastrophic    (AC)
 *
 *    6) Child  Platinum        (CP)
 *    7) Child  Gold            (CG)
 *    8) Child  Silver          (CS)
 *    9) Child  Bronze          (CB)
 *   10) Child  Catastrophic    (CC)
 *
 *   11) Infant Platinum        (IP)
 *   12) Infant Gold            (IG)
 *   13) Infant Silver          (IS)
 *   14) Infant Bronze          (IB)
 *   15) Infant Catastrophic    (IC).
 *
 * ICD-10-CM diagnosis codes are accepted in this version. 
 *
 * All the input SAS datasets, PERSON, DIAG, HCPCS and NDC, must be ordered by enrollee ID, i.e.,
 * the user must ensure that each dataset is sorted by the common identifier.
 * The PERSON dataset must not contain duplicate enrollee IDs. The enrollee ID 
 * is named in the user-provided macro variable &IDVAR.
 *
 * The PERSON SAS dataset must contain the following variables and values:
 *  &IDVAR        - unique enrollee ID (e.g., Medicare HICNO), character or numeric,
 *                   any valid length, not missing, no duplicates
 *  DOB           - date of birth, numeric, yyyymmdd, valid calendar date
 *  AGE_LAST      - age as of last day of enrollment in benefit year, numeric, 0/1/2/...
 *  SEX           - sex, character, M/F/m/f/1/2, if lower case automatically converted
 *  METAL         - enrollee`s plan level, character, P/G/S/B/C/p/g/s/b/c, if lower case 
 *                   automatically converted
 *  CSR_INDICATOR - cost sharing reduction indicator, numeric, 0/1/2/3/4/5/6/7/8/9/10/11/12/13
 *  ENROLDURATION - number of months enrollee was in plan (1 to 12)
 *
 * The DIAG SAS dataset must contain the following variables and values:
 *  &IDVAR        - unique enrollee ID (e.g., Medicare HICNO), character or numeric,
 *                   any valid length, not missing
 *  DIAG          - ICD-10-CM diagnosis, character, 3-8 bytes, no decimal point, no
 *                   embedded blanks in code, if lower case automatically converted
 *  DIAGNOSIS_SERVICE_DATE - date of diagnosis, numeric, yyyymmdd, valid calendar date
 *
 *  If an enrollee has N diagnoses, s/he will have N records in the DIAG dataset. If an
 *  enrollee has no diagnoses, s/he will have zero records in the DIAG dataset.
 *
 *  AGE_AT_DIAGNOSIS, the age as of the diagnosis service date, is calculated by the 
 *   software using DOB from the PERSON dataset and DIAGNOSIS_SERVICE_DATE from the  
 *   DIAGNOSIS dataset. It is used only for MCE diagnosis code age edits.
 *
 * The NDC SAS dataset must contain the following variables and values:
 *  &IDVAR        - unique enrollee ID (e.g., Medicare HICNO), character or numeric,
 *                   any valid length, not missing
 *  NDC           - NDC code, character 11 bytes, any valid format for NDC codes.
 *
 *  If an enrollee has N NDC codes, s/he will have N records in the NDC dataset. If an
 *  enrollee has no NDC codes, s/he will have zero records in the NDC dataset.
 *
 * The HCPCS SAS dataset must contain the following variables and values:
 *  &IDVAR        - unique enrollee ID (e.g., Medicare HICNO), character or numeric,
 *                   any valid length, not missing
 *  HCPCS         - HCPCS code, character 5 bytes, CPT coding format.
 *
 *  If an enrollee has N HCPC codes, s/he will have N records in the HCPCS dataset. If an
 *  enrollee has no HCPC codes, s/he will have zero records in the HCPCS dataset.
 *
 *  V0520F4P passes parameters to main macro V0520F4M, which calls various internal and
 *    external macros. (A macro is a program fragment.) External macros are:
 *  I0V05ED4 - ICD10 edits based on age and/or sex
 *  AGESEXV6 - creates age/sex variables based on AGE_LAST
 *  V05128L1 - assigns labels to HHS HCCs and RXCs
 *  V05128H1 - sets selected HHS HCCs to zero based on hierarchical relationships
 *  SCOREV4  - calculates score variables.
 *
 * A SAS format that maps ICD10s to CCs is required. The format is specified as
 * parameter CCFMT0 (for ICD10) in the main macro call. A SAS format that maps
 * NDCs to RXCs is required. The format is specified as parameter RXCFMTN in the 
 * main macro call. A SAS format that maps HCPCS to RXCs is required. The format
 * is specified as parameter RXCFMTH in the main macro call.
 *
 * Program steps: The program(s):
 * Include external macros. The external macros are most likely to vary
 *     among releases.
 * Define internal macro variables, formats, internal macros. The
 *     internal macros are least likely to vary among releases.
 * Merge PERSON, DIAG, NDC, and HCPCS datasets, and output one record for each
 *     enrollee record in the PERSON dataset. Output records must be fully
 *     compliant with validity rules (e.g., SEX must be M/m/F/f/1/2).
 *     Exceptions are ignored. Warning messages are generated for some 
 *     exceptions.
 * Declare lengths, retained variables, arrays
 * Append calibration coefficients
 * Merge PERSON, DIAG, NDC, and HCPCS datasets by &IDVAR
 * If there are any diagnoses for an enrollee:
 *   - perform ICD10 edits
 *   - create additional (multiple) CCs for selected diagnoses
 *   - create age/sex variables
 *   - create RXC variables
 *   - create HCCs with hierarchy rules
 *   - set HCCs to zero if there are no diagnoses for enrollee 
 *   - apply validity filters 
 *   - create additional model-specific variables 
 *   - create scores 
 *   - define formats, labels. 
 * Contents and data dump
 *
 * User inputs:
 * The user provides four SAS datasets with the variables described above,
 * each sorted by &IDVAR, and sets the following parameters in the macro call:
 *  INP      - SAS input PERSON SAS dataset
 *  IND      - SAS input DIAG SAS dataset
 *  INN      - SAS input NDC SAS dataset
 *  INH      - SAS input HCPCS SAS dataset
 *  OUTDATA  - SAS output SAS dataset
 *  IDVAR    - name of enrollee ID variable (e.g., Medicare HICNO)
 *  KEEPVAR  - variables in output dataset in addition to &IDVAR
 *  CCFMT0Y1 - pointer to SAS formats that crosswalk ICD10s to HHS CCs for fiscal year 2020
 *  CCFMT0Y2 - pointer to SAS formats that crosswalk ICD10s to HHS CCs for fiscal year 2021 
 *  RXCFMTN  - pointer to SAS formats that crosswalk NDC to RXC for calendar year 2020
 *  RXCFMTH  - pointer to SAS formats that crosswalk HCPCS to RXC for calendar year 2020
 *  AGEFMT0  - pointer to SAS formats that crosswalk ICD10s to acceptable 
 *             age range in case age-related edits are to be performed
 *  SEXFMT0  - pointer to SAS format that crosswalks ICD10s to acceptable 
 *             sex in case sex-related edits are to be performed
 *
 * Platforms: software has been tested with SAS v9.4 on Linux (Intel server,
 * Red Hat).
