Loading a block (LB)
The LB (LoadBlock) function can be used to load blocks containing subprograms
during operation.
LB should be configured in a LOAD method so that the loaded subprograms can
be called at any time.
LB("Block name"[,"File"])
where:
Block name Name of block identifier
File Path name of configuration file
Default setting: Current configuration file
LOAD
LB("PROG1") ;Block "PROG1" is located in the current configuration file
;and then loaded
LB("PROG2","C:\TMP\XY.COM")
;Block "PROG2" is located in configuration file XY.COM in the
;C:\TMP directory and then loaded
END_LOAD
Note
Subprograms can also be defined directly in a screen form so that they do not
have to be loaded.
Indirect subprogram call (CALL)
The CALL function can be used to call a loaded subprogram from any point in a
method.
Subprogram nesting is supported, i.e., you can call a subprogram from another
subprogram.
CALL("Identifier")
where:
Identifier Name of subprogram
//M(FORM1)
VAR1 = ...
VAR2 = ...
