Indirectly programming part program lines (EXECSTRING)

Function
Using the part program command EXECSTRING, it is possible to execute a previously
generated string variable as part program line.
Syntax
EXECSTRING is programmed in a separate part program line:
EXECSTRING (<string_variable>)
Meaning
EXECSTRING:
<string variable>:
Note
With EXECSTRING all part program constructions that can be programmed in the program
section of a part program can be extracted. This means that PROC and DEF instructions are
excluded as well as the general use in INI and DEF files.
Example
Program code
N100 DEF STRING[100] BLOCK
N110 DEF STRING[10] MFCT1="M7"
...
N200 EXECSTRING(MFCT1 << "M4711")
...
N300 R10=1
N310 BLOCK="M3"
N320 IF(R10)
N330 BLOCK = BLOCK << MFCT1
N340 ENDIF
N350 EXECSTRING(BLOCK)
