Vínculo do Programa Assembler - Exemplo

O código a seguir exibe um exemplo de vínculo do programa Assembler: 
L     R3,0(R1)                get address of argument 1
         L     R4,0(R3)                get NumberFields value
         C     R4,=F'2'                Required value of 2 ?

No exemplo de programa, dois campos são passados para o programa Assembler. O primeiro campo é chamado TEXT. Os dados podem ser movidos para ele e dele usando o quarto endereço na lista - o endereço em 12(R1). Se ele não for um campo CHAR de tamanho fixo, use o tamanho dos dados para determinar o tamanho real do endereço em 16(R1).
