Re: Alternating tables

[Rob Berendt <rob@xxxxxxxxx>]

I'm a different Rob, but I'll take a stab.  Let's use a simple table:

While this might be better in a lookup file, for the sake of our example let's 
assume we used a compile time table.

¦   DName+++++++++++ETDsFrom+++To/L+++IDc.Keywords++++++++++++++++++++          
                   ¦
¦   DTABEMP                          3A 0 DIM(4) PERRCD(1) CTDATA               
                   ¦
¦   DTABPAY                          7S 2 DIM(4) ALT(TABEMP)                    
                   ¦
¦   CL0N01Factor1+++++++Opcode(E)+Factor2+++++++Result++++++++Len++D+HiLoEq..   
                   ¦
¦   C* The LOOKUP operation searches TABEMP for an entry that is equal to       
                   ¦
¦   C* the contents of the field named EMPNUM. If an equal entry is             
                   ¦
¦   C* found in TABEMP, indicator 09 is set on, and the TABEMP entry and        
                   ¦
¦   C* its related entry in TABPAY are made the current elements.               
                   ¦
¦   C     EMPNUM        LOOKUP    TABEMP        TABPAY                   09     
                   ¦
¦   C* If indicator 09 is set on, the contents of the field named               
                   ¦
¦   C* HRSWKD are multiplied by the value of the current element of             
                   ¦
¦   C* TABPAY.                                                                  
                   ¦
¦   C                   IF        *IN09                                         
                   ¦
¦   C     HRSWKD        MULT(H)   TABPAY        AMT               6 2           
                   ¦
¦   C                   ENDIF                                                   
                   ¦
     ...
