Hi all

I encountered a strange(strange to me) question when coding a ASM table, like
Code:

TABLE      EQU   *
               ..............
               DC    C'7C @'
               DC    C'7B #'
               DC    C'5B $'
               DC    C'6C %'
               DC    C'50 &'
TABLEND  EQU   *     
               END   

following is the compiled list of the section:
Code:

                      0009C          61 TABLE    EQU   *           
                                         ...............................................
000150 F7C3407C                     107          DC    C'7C @'
000154 F7C2407B                     108          DC    C'7B #'
000158 F5C2405B                     109          DC    C'5B $'
00015C F6C3406C                     110          DC    C'6C %'
                                    111          DC    C'50 &'
HEXTOCH  HEX CHARACTER VALUE TO CHARACTER                     
  Active Usings: HEXTOCH,R12                                 
  Loc  Object Code    Addr1 Addr2  Stmt   Source Statement   
                                       +         DC         &'
** ASMA040S Missing operand                                   
** ASMA024E Invalid variable symbol - '                       
** ASMA435I Record 111 in ZOSDV1.ZOS5501.SOURCE(HEXTOCH) on vo
                      00160         112 TABLEND  EQU   *     
                                    113          END         

well , one more line appears in the compiled list, anyone knows why?
and when i got rid of the last line(DC C'50 &') , it returns normal.

The ampersand is a special character to the assembler.

Solution is to double the special characters that are part of the data(apsotrophes, ampersands) and it assembles as one char:
Code:
     DC    C'50 &&'
or
   DC  C'This is Bob''s'
