GV_ZALVL = '%ALVL'.

ASSIGN (GV_ZALVL) TO <ALVL>.

GV_ZVARI = '/1'.

%ALVL will be assigned the value /1. Please see the explanation below.

GV_ZALVL = '%ALVL'.

GV_ZALVL is assigned the value %ALVL. %ALVL might be an variable in your program.

ASSIGN (GV_ZALVL) TO <ALVL>.

Content of the field %ALVL ia assigned to the field symbol <ALVL>

GV_ZVARI = '/1'.

GV_ZALVL is assigned the value /1.

<ALVL> = GV_ZVARI.

This statement will assign /1 to the variable %ALVL.

Hi,

Kindly find my answers below ur questions...

Reward points if helpful..

GV_ZALVL = '%ALVL'.

<b>%ALVL -- SAP STANDARD FUNCTION CODES are represented this way.</b>

GV_ZVARI = '/1'.

<b>A Function Code (f1 fUNCTION KEY) is passed.</b>

ASSIGN (GV_ZALVL) TO <ALVL>.

<b>Here <ALVL> is a field-symbol, it has to be declared before this statement occurs. Field-symbols have to be assigned to any object before using them. Field-symbols are used to dynamically refer to the address of a object in runtime. Field-symbols can be related to Dereferenced Pointers in C.</b>

For further reference on Field-symbols refer to SAP HELP DOCUMENT.

Hope the info. is helpful, if any more clarifications revert back, else close the thread.

Reward points if convinced with the answer.
